Given numbers are 421, 920, 665, 437

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 665 are 5 x 7 x 19

Prime factors of 437 are 19 x 23

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

Given numbers are 421, 920, 665, 437

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

Apply this formula for all numbers.

Step1:

LCM(421, 920) = 387320

GCD(421, 920) = ( 421 x 920 ) / 387320

= 421 / 920

= 421

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 421, 920, 665, 437 is 1
