Given numbers are 678, 647, 650, 156

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 647 are 647

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 156 are 2 x 2 x 3 x 13

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

Given numbers are 678, 647, 650, 156

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

Apply this formula for all numbers.

Step1:

LCM(678, 647) = 438666

GCD(678, 647) = ( 678 x 647 ) / 438666

= 678 / 647

= 678

Step2:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 678, 647, 650, 156 is 1
