Given numbers are 420, 640, 219, 151

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 219 are 3 x 73

Prime factors of 151 are 151

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

Given numbers are 420, 640, 219, 151

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

Apply this formula for all numbers.

Step1:

LCM(420, 640) = 13440

GCD(420, 640) = ( 420 x 640 ) / 13440

= 420 / 640

= 420

Step2:

LCM(20, 219) = 4380

GCD(20, 219) = ( 20 x 219 ) / 4380

= 20 / 219

= 20

Step3:

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

= 1 / 151

= 1

So, Greatest Common Divisor of 420, 640, 219, 151 is 1
