Given numbers are 658, 356, 395, 442

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 356 are 2 x 2 x 89

Prime factors of 395 are 5 x 79

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 658, 356, 395, 442

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

Apply this formula for all numbers.

Step1:

LCM(658, 356) = 117124

GCD(658, 356) = ( 658 x 356 ) / 117124

= 658 / 356

= 658

Step2:

LCM(2, 395) = 790

GCD(2, 395) = ( 2 x 395 ) / 790

= 2 / 395

= 2

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 658, 356, 395, 442 is 1
