Given numbers are 151, 357, 777, 420

The list of prime factors of all numbers are

Prime factors of 151 are 151

Prime factors of 357 are 3 x 7 x 17

Prime factors of 777 are 3 x 7 x 37

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 151, 357, 777, 420

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

Apply this formula for all numbers.

Step1:

LCM(151, 357) = 53907

GCD(151, 357) = ( 151 x 357 ) / 53907

= 151 / 357

= 151

Step2:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 151, 357, 777, 420 is 1
