Given numbers are 374, 163, 280, 642

The list of prime factors of all numbers are

Prime factors of 374 are 2 x 11 x 17

Prime factors of 163 are 163

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 374, 163, 280, 642

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

Apply this formula for all numbers.

Step1:

LCM(374, 163) = 60962

GCD(374, 163) = ( 374 x 163 ) / 60962

= 374 / 163

= 374

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 374, 163, 280, 642 is 1
