Given numbers are 658, 318, 644, 731

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 318 are 2 x 3 x 53

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 731 are 17 x 43

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

Given numbers are 658, 318, 644, 731

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

Apply this formula for all numbers.

Step1:

LCM(658, 318) = 104622

GCD(658, 318) = ( 658 x 318 ) / 104622

= 658 / 318

= 658

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 731) = 1462

GCD(2, 731) = ( 2 x 731 ) / 1462

= 2 / 731

= 2

So, Greatest Common Divisor of 658, 318, 644, 731 is 1
