Given numbers are 680, 486, 724, 765

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 724 are 2 x 2 x 181

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 680, 486, 724, 765

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

Apply this formula for all numbers.

Step1:

LCM(680, 486) = 165240

GCD(680, 486) = ( 680 x 486 ) / 165240

= 680 / 486

= 680

Step2:

LCM(2, 724) = 724

GCD(2, 724) = ( 2 x 724 ) / 724

= 2 / 724

= 2

Step3:

LCM(2, 765) = 1530

GCD(2, 765) = ( 2 x 765 ) / 1530

= 2 / 765

= 2

So, Greatest Common Divisor of 680, 486, 724, 765 is 1
