The greatest common factor (GCF) of 63, 21, and 7 is 7.
The GCF is 7.
The GCF is 7.
The GCF is 21.
The LCM is: 441The GCF is: 7
The GCF is 21.
The GCF of 49 and 63 is 7. The greatest common factor is the highest number that divides exactly into two or more numbers. 49: 1, 7, 49 63: 1, 3, 7, 9, 21, 63
The greatest common factor of 21 and 63 is 21.Since 21 is a factor of 63, it is automatically the GCF.
The GCF of 21, 35, and 63 is 7.
The GCF is 7.
The GCF of 21, 56, 63, and 84 is 7.
To find the greatest common factor (GCF) of 21, 49, and 63, we first need to find the prime factorization of each number. The prime factorization of 21 is 3 x 7, 49 is 7 x 7, and 63 is 3 x 3 x 7. The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers, which in this case is 7. Therefore, the GCF of 21, 49, and 63 is 7.
The GCF is 7.
