Given numbers are 420, 458, 791, 218

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 458 are 2 x 229

Prime factors of 791 are 7 x 113

Prime factors of 218 are 2 x 109

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

Given numbers are 420, 458, 791, 218

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

Apply this formula for all numbers.

Step1:

LCM(420, 458) = 96180

GCD(420, 458) = ( 420 x 458 ) / 96180

= 420 / 458

= 420

Step2:

LCM(2, 791) = 1582

GCD(2, 791) = ( 2 x 791 ) / 1582

= 2 / 791

= 2

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 420, 458, 791, 218 is 1
