Writing down all the factors of both numbers requires too much time so it is not a good idea to find solution by writing each factor of both numbers.
Method of prime factorization is one of the good methods to find GCF.
Prime factorization is like breaking a number into other numbers, prime numbers, and this factorization is unique. Prime factorization is like a blueprint for numbers.
Prime factorization of 1820 = 22 x 5 x 7 x 13
Prime factorization of 637 = 7 x 7 x 13
7, 13 and 7x13 are common in the prime factorization of both numbers, but 7x13 is the greatest among these numbers. So, 7x13 = 91 is the GCF of 1820 and 637.
