Given numbers are 658, 693, 515, 542

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

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

Prime factors of 515 are 5 x 103

Prime factors of 542 are 2 x 271

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

Given numbers are 658, 693, 515, 542

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

Apply this formula for all numbers.

Step1:

LCM(658, 693) = 65142

GCD(658, 693) = ( 658 x 693 ) / 65142

= 658 / 693

= 658

Step2:

LCM(7, 515) = 3605

GCD(7, 515) = ( 7 x 515 ) / 3605

= 7 / 515

= 7

Step3:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

So, Greatest Common Divisor of 658, 693, 515, 542 is 1
