Given numbers are 353, 777, 130, 420

The list of prime factors of all numbers are

Prime factors of 353 are 353

Prime factors of 777 are 3 x 7 x 37

Prime factors of 130 are 2 x 5 x 13

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 353, 777, 130, 420

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

Apply this formula for all numbers.

Step1:

LCM(353, 777) = 274281

GCD(353, 777) = ( 353 x 777 ) / 274281

= 353 / 777

= 353

Step2:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 353, 777, 130, 420 is 1
