Given numbers are 678, 770, 530, 157

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 530 are 2 x 5 x 53

Prime factors of 157 are 157

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 678, 770, 530, 157

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(678, 770) = 261030

GCD(678, 770) = ( 678 x 770 ) / 261030

= 678 / 770

= 678

Step2:

LCM(2, 530) = 530

GCD(2, 530) = ( 2 x 530 ) / 530

= 2 / 530

= 2

Step3:

LCM(2, 157) = 314

GCD(2, 157) = ( 2 x 157 ) / 314

= 2 / 157

= 2

So, Greatest Common Divisor of 678, 770, 530, 157 is 1
