What is the greatest common factor of 21 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.
