Given numbers are 658, 420, 411, 577

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

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

Prime factors of 411 are 3 x 137

Prime factors of 577 are 577

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

Given numbers are 658, 420, 411, 577

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

Apply this formula for all numbers.

Step1:

LCM(658, 420) = 19740

GCD(658, 420) = ( 658 x 420 ) / 19740

= 658 / 420

= 658

Step2:

LCM(14, 411) = 5754

GCD(14, 411) = ( 14 x 411 ) / 5754

= 14 / 411

= 14

Step3:

LCM(1, 577) = 577

GCD(1, 577) = ( 1 x 577 ) / 577

= 1 / 577

= 1

So, Greatest Common Divisor of 658, 420, 411, 577 is 1
