Given numbers are 463, 660, 640, 780

The list of prime factors of all numbers are

Prime factors of 463 are 463

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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 463, 660, 640, 780

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

Apply this formula for all numbers.

Step1:

LCM(463, 660) = 305580

GCD(463, 660) = ( 463 x 660 ) / 305580

= 463 / 660

= 463

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 463, 660, 640, 780 is 1
