Given numbers are 780, 412, 709, 663

The list of prime factors of all numbers are

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

Prime factors of 412 are 2 x 2 x 103

Prime factors of 709 are 709

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 780, 412, 709, 663

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

Apply this formula for all numbers.

Step1:

LCM(780, 412) = 80340

GCD(780, 412) = ( 780 x 412 ) / 80340

= 780 / 412

= 780

Step2:

LCM(4, 709) = 2836

GCD(4, 709) = ( 4 x 709 ) / 2836

= 4 / 709

= 4

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 780, 412, 709, 663 is 1
