Given numbers are 420, 164, 677, 760

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 164 are 2 x 2 x 41

Prime factors of 677 are 677

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

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

Given numbers are 420, 164, 677, 760

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

Apply this formula for all numbers.

Step1:

LCM(420, 164) = 17220

GCD(420, 164) = ( 420 x 164 ) / 17220

= 420 / 164

= 420

Step2:

LCM(4, 677) = 2708

GCD(4, 677) = ( 4 x 677 ) / 2708

= 4 / 677

= 4

Step3:

LCM(1, 760) = 760

GCD(1, 760) = ( 1 x 760 ) / 760

= 1 / 760

= 1

So, Greatest Common Divisor of 420, 164, 677, 760 is 1
