Given numbers are 780, 125, 946, 640

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 125 are 5 x 5 x 5

Prime factors of 946 are 2 x 11 x 43

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

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

Given numbers are 780, 125, 946, 640

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

Apply this formula for all numbers.

Step1:

LCM(780, 125) = 19500

GCD(780, 125) = ( 780 x 125 ) / 19500

= 780 / 125

= 780

Step2:

LCM(5, 946) = 4730

GCD(5, 946) = ( 5 x 946 ) / 4730

= 5 / 946

= 5

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 780, 125, 946, 640 is 1
