Below you can find the full step by step solution for you problem. We hope it will be very helpful for you and it will help you to understand the solving process.

If it's not what You are looking for type in the calculator fields your own values, and You will get the solution.

To find the greatest common factor of two numbers just type them in and get the solution.

To get the Greates Common Factor (GCF) of 561 and 1353 we need to factor each value first and then we choose all the copies of factors and multiply them:

561: | 3 | 11 | 17 | |

1353: | 3 | 11 | 41 | |

GCF: | 3 | 11 |

**The Greates Common Factor (GCF) is: 3 x 11 = 33**

| Greatest Common Factor (GCF) of 495 and 121 | | Greatest Common Factor (GCF) of 12 and 0.25 | | Greatest Common Factor (GCF) of 360000 and 336000 | | Greatest Common Factor (GCF) of 24000 and 360000 | | Greatest Common Factor (GCF) of 20123 and 9990 | | Greatest Common Factor (GCF) of 194 and 211 | | Greatest Common Factor (GCF) of 321 and 168 | | Greatest Common Factor (GCF) of 30303 and 1000000 | | Greatest Common Factor (GCF) of 551 and 80 | | Greatest Common Factor (GCF) of 1827 and 60 | | Greatest Common Factor (GCF) of 2295 and 900 | | Greatest Common Factor (GCF) of 800 and 475 | | Greatest Common Factor (GCF) of 57375 and 100000 | | Greatest Common Factor (GCF) of 210200 and 15 | | Greatest Common Factor (GCF) of 7536 and 360 | | Greatest Common Factor (GCF) of 365 and 1936 | | Greatest Common Factor (GCF) of 295 and 638 | | Greatest Common Factor (GCF) of 1004 and 10 | | Greatest Common Factor (GCF) of 4215 and 3289 | | Greatest Common Factor (GCF) of 10000 and 50 | | Greatest Common Factor (GCF) of 53 and 855 | | Greatest Common Factor (GCF) of 494 and 231 | | Greatest Common Factor (GCF) of 16 and 3166 | | Greatest Common Factor (GCF) of 110 and 588 | | Greatest Common Factor (GCF) of 14641 and 14161 | | Greatest Common Factor (GCF) of 121 and 1119 | | Greatest Common Factor (GCF) of 509 and 102 | | Greatest Common Factor (GCF) of 463 and 29 | | Greatest Common Factor (GCF) of 999 and 564 | | Greatest Common Factor (GCF) of 0.125 and 0.152 | | Greatest Common Factor (GCF) of 25 and 4347 | | Greatest Common Factor (GCF) of 125 and 529 |
