Given numbers are 658, 440, 117, 280

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 117 are 3 x 3 x 13

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 658, 440, 117, 280

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

Apply this formula for all numbers.

Step1:

LCM(658, 440) = 144760

GCD(658, 440) = ( 658 x 440 ) / 144760

= 658 / 440

= 658

Step2:

LCM(2, 117) = 234

GCD(2, 117) = ( 2 x 117 ) / 234

= 2 / 117

= 2

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 658, 440, 117, 280 is 1
