Given numbers are 658, 421, 609, 270

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 421 are 421

Prime factors of 609 are 3 x 7 x 29

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

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

Given numbers are 658, 421, 609, 270

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

Apply this formula for all numbers.

Step1:

LCM(658, 421) = 277018

GCD(658, 421) = ( 658 x 421 ) / 277018

= 658 / 421

= 658

Step2:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

Step3:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

So, Greatest Common Divisor of 658, 421, 609, 270 is 1
