Given numbers are 157, 100, 345, 672

The list of prime factors of all numbers are

Prime factors of 157 are 157

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

Prime factors of 345 are 3 x 5 x 23

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 157, 100, 345, 672

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

Apply this formula for all numbers.

Step1:

LCM(157, 100) = 15700

GCD(157, 100) = ( 157 x 100 ) / 15700

= 157 / 100

= 157

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 157, 100, 345, 672 is 1
