Given numbers are 658, 451, 693, 646

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 451 are 11 x 41

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 658, 451, 693, 646

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

Apply this formula for all numbers.

Step1:

LCM(658, 451) = 296758

GCD(658, 451) = ( 658 x 451 ) / 296758

= 658 / 451

= 658

Step2:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 658, 451, 693, 646 is 1
