Given numbers are 455, 381, 656, 900

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 381 are 3 x 127

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

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

Given numbers are 455, 381, 656, 900

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

Apply this formula for all numbers.

Step1:

LCM(455, 381) = 173355

GCD(455, 381) = ( 455 x 381 ) / 173355

= 455 / 381

= 455

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

= 1 / 900

= 1

So, Greatest Common Divisor of 455, 381, 656, 900 is 1
