Given numbers are 665, 574, 420, 118

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 574 are 2 x 7 x 41

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

Prime factors of 118 are 2 x 59

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

Given numbers are 665, 574, 420, 118

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

Apply this formula for all numbers.

Step1:

LCM(665, 574) = 54530

GCD(665, 574) = ( 665 x 574 ) / 54530

= 665 / 574

= 665

Step2:

LCM(7, 420) = 420

GCD(7, 420) = ( 7 x 420 ) / 420

= 7 / 420

= 7

Step3:

LCM(7, 118) = 826

GCD(7, 118) = ( 7 x 118 ) / 826

= 7 / 118

= 7

So, Greatest Common Divisor of 665, 574, 420, 118 is 1
