Given numbers are 621, 688, 495, 158

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 158 are 2 x 79

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

Given numbers are 621, 688, 495, 158

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

Apply this formula for all numbers.

Step1:

LCM(621, 688) = 427248

GCD(621, 688) = ( 621 x 688 ) / 427248

= 621 / 688

= 621

Step2:

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

= 1 / 495

= 1

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 621, 688, 495, 158 is 1
