Given numbers are 151, 454, 780, 474

The list of prime factors of all numbers are

Prime factors of 151 are 151

Prime factors of 454 are 2 x 227

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

Prime factors of 474 are 2 x 3 x 79

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

Given numbers are 151, 454, 780, 474

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

Apply this formula for all numbers.

Step1:

LCM(151, 454) = 68554

GCD(151, 454) = ( 151 x 454 ) / 68554

= 151 / 454

= 151

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 151, 454, 780, 474 is 1
