Given numbers are 454, 287, 780, 976

The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 287 are 7 x 41

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 976 are 2 x 2 x 2 x 2 x 61

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

Given numbers are 454, 287, 780, 976

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

Apply this formula for all numbers.

Step1:

LCM(454, 287) = 130298

GCD(454, 287) = ( 454 x 287 ) / 130298

= 454 / 287

= 454

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 976) = 976

GCD(1, 976) = ( 1 x 976 ) / 976

= 1 / 976

= 1

So, Greatest Common Divisor of 454, 287, 780, 976 is 1
