Given numbers are 638, 973, 516, 100

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 973 are 7 x 139

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

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

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

Given numbers are 638, 973, 516, 100

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

Apply this formula for all numbers.

Step1:

LCM(638, 973) = 620774

GCD(638, 973) = ( 638 x 973 ) / 620774

= 638 / 973

= 638

Step2:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

Step3:

LCM(1, 100) = 100

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

= 1 / 100

= 1

So, Greatest Common Divisor of 638, 973, 516, 100 is 1
