42 & 49 !
To find the greatest common factor of 21, 42, and 49, we first need to find the prime factors of each number. The prime factors of 21 are 3 and 7, the prime factors of 42 are 2, 3, and 7, and the prime factors of 49 are 7 and 7. The greatest common factor is the product of the common prime factors raised to the lowest power they appear in any of the numbers, which in this case is 7. Therefore, the greatest common factor of 21, 42, and 49 is 7.
Factors of 42: 1, 2, 3, 6, 7, 14, 21, and 42. Factors of 49: 1, 7, and 49.
The greatest common factor (GCF) of 35, 42, and 49 is 7. To find the GCF, you need to determine the factors of each number and then identify the largest factor that is common to all three numbers. In this case, the factors of 35 are 1, 5, 7, 35; the factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42; and the factors of 49 are 1, 7, 49. The largest factor that is common to all three numbers is 7, making it the greatest common factor.
