Given numbers are 938, 163, 645, 450

The list of prime factors of all numbers are

Prime factors of 938 are 2 x 7 x 67

Prime factors of 163 are 163

Prime factors of 645 are 3 x 5 x 43

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

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

Given numbers are 938, 163, 645, 450

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

Apply this formula for all numbers.

Step1:

LCM(938, 163) = 152894

GCD(938, 163) = ( 938 x 163 ) / 152894

= 938 / 163

= 938

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 938, 163, 645, 450 is 1
