Easiest way to find the gcf of two numbers
WebMar 26, 2016 · The greatest number that appears on both lists is 15. The GCF of 27 and 72 is 9. Decompose 27 and 72 into their prime factors and underline every factor that’s common to both: 27 = 3 x 3 x 3. 72 = 2 x 2 x 2 x 3 x 3. Multiply those underlined numbers to get your answer: 3 x 3 = 9. The GCF of 15, 20, and 35 is 5. WebTo find the greatest common factor (GCF) of 33, 77, and 121, we can start by finding the prime factors of each number: 33 = 3 x 11 77 = 7 x 11 121 = 11 x 11 Now, we can identify the common prime factors of these numbers, which is 11. Therefore, the GCF of 33, 77, and 121 is 11. 1 Sponsored by Grammarly
