Given numbers are 420, 641, 319, 101

The list of prime factors of all numbers are

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

Prime factors of 641 are 641

Prime factors of 319 are 11 x 29

Prime factors of 101 are 101

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

Given numbers are 420, 641, 319, 101

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

Apply this formula for all numbers.

Step1:

LCM(420, 641) = 269220

GCD(420, 641) = ( 420 x 641 ) / 269220

= 420 / 641

= 420

Step2:

LCM(1, 319) = 319

GCD(1, 319) = ( 1 x 319 ) / 319

= 1 / 319

= 1

Step3:

LCM(1, 101) = 101

GCD(1, 101) = ( 1 x 101 ) / 101

= 1 / 101

= 1

So, Greatest Common Divisor of 420, 641, 319, 101 is 1
