Given numbers are 100, 788, 421

The list of prime factors of all numbers are

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

Prime factors of 788 are 2 x 2 x 197

Prime factors of 421 are 421

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

Given numbers are 100, 788, 421

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

Apply this formula for all numbers.

Step1:

LCM(100, 788) = 19700

GCD(100, 788) = ( 100 x 788 ) / 19700

= 100 / 788

= 100

Step2:

LCM(4, 421) = 1684

GCD(4, 421) = ( 4 x 421 ) / 1684

= 4 / 421

= 4

So, Greatest Common Divisor of 100, 788, 421 is 1
