Given numbers are 455, 147, 456, 756

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 147 are 3 x 7 x 7

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 455, 147, 456, 756

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

Apply this formula for all numbers.

Step1:

LCM(455, 147) = 9555

GCD(455, 147) = ( 455 x 147 ) / 9555

= 455 / 147

= 455

Step2:

LCM(7, 456) = 3192

GCD(7, 456) = ( 7 x 456 ) / 3192

= 7 / 456

= 7

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 455, 147, 456, 756 is 1
