Given numbers are 676, 516, 247, 128

The list of prime factors of all numbers are

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 247 are 13 x 19

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 676, 516, 247, 128

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

Apply this formula for all numbers.

Step1:

LCM(676, 516) = 87204

GCD(676, 516) = ( 676 x 516 ) / 87204

= 676 / 516

= 676

Step2:

LCM(4, 247) = 988

GCD(4, 247) = ( 4 x 247 ) / 988

= 4 / 247

= 4

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 676, 516, 247, 128 is 1
