Given numbers are 421, 528, 811, 120

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 811 are 811

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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

Given numbers are 421, 528, 811, 120

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

Apply this formula for all numbers.

Step1:

LCM(421, 528) = 222288

GCD(421, 528) = ( 421 x 528 ) / 222288

= 421 / 528

= 421

Step2:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 421, 528, 811, 120 is 1
