Given numbers are 658, 509, 624, 721

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 509 are 509

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 721 are 7 x 103

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

Given numbers are 658, 509, 624, 721

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

Apply this formula for all numbers.

Step1:

LCM(658, 509) = 334922

GCD(658, 509) = ( 658 x 509 ) / 334922

= 658 / 509

= 658

Step2:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 658, 509, 624, 721 is 1
