Given numbers are 645, 730, 518, 646

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 730 are 2 x 5 x 73

Prime factors of 518 are 2 x 7 x 37

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 645, 730, 518, 646

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

Apply this formula for all numbers.

Step1:

LCM(645, 730) = 94170

GCD(645, 730) = ( 645 x 730 ) / 94170

= 645 / 730

= 645

Step2:

LCM(5, 518) = 2590

GCD(5, 518) = ( 5 x 518 ) / 2590

= 5 / 518

= 5

Step3:

LCM(1, 646) = 646

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

= 1 / 646

= 1

So, Greatest Common Divisor of 645, 730, 518, 646 is 1
