Given numbers are 420, 665, 554, 487

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 665 are 5 x 7 x 19

Prime factors of 554 are 2 x 277

Prime factors of 487 are 487

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

Given numbers are 420, 665, 554, 487

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

Apply this formula for all numbers.

Step1:

LCM(420, 665) = 7980

GCD(420, 665) = ( 420 x 665 ) / 7980

= 420 / 665

= 420

Step2:

LCM(35, 554) = 19390

GCD(35, 554) = ( 35 x 554 ) / 19390

= 35 / 554

= 35

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 420, 665, 554, 487 is 1
