Given numbers are 713, 646, 727, 780

The list of prime factors of all numbers are

Prime factors of 713 are 23 x 31

Prime factors of 646 are 2 x 17 x 19

Prime factors of 727 are 727

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 713, 646, 727, 780

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

Apply this formula for all numbers.

Step1:

LCM(713, 646) = 460598

GCD(713, 646) = ( 713 x 646 ) / 460598

= 713 / 646

= 713

Step2:

LCM(1, 727) = 727

GCD(1, 727) = ( 1 x 727 ) / 727

= 1 / 727

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 713, 646, 727, 780 is 1
