Given numbers are 455, 220, 76

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 76 are 2 x 2 x 19

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

Given numbers are 455, 220, 76

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

Apply this formula for all numbers.

Step1:

LCM(455, 220) = 20020

GCD(455, 220) = ( 455 x 220 ) / 20020

= 455 / 220

= 455

Step2:

LCM(5, 76) = 380

GCD(5, 76) = ( 5 x 76 ) / 380

= 5 / 76

= 5

So, Greatest Common Divisor of 455, 220, 76 is 1
