Given numbers are 763, 405, 440, 646

The list of prime factors of all numbers are

Prime factors of 763 are 7 x 109

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 440 are 2 x 2 x 2 x 5 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 763, 405, 440, 646

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

Apply this formula for all numbers.

Step1:

LCM(763, 405) = 309015

GCD(763, 405) = ( 763 x 405 ) / 309015

= 763 / 405

= 763

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 646) = 646

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

= 1 / 646

= 1

So, Greatest Common Divisor of 763, 405, 440, 646 is 1
