Given numbers are 747, 151, 100, 646

The list of prime factors of all numbers are

Prime factors of 747 are 3 x 3 x 83

Prime factors of 151 are 151

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 747, 151, 100, 646

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

Apply this formula for all numbers.

Step1:

LCM(747, 151) = 112797

GCD(747, 151) = ( 747 x 151 ) / 112797

= 747 / 151

= 747

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 747, 151, 100, 646 is 1
