Given numbers are 780, 416, 975, 154

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 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 780, 416, 975, 154

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

Apply this formula for all numbers.

Step1:

LCM(780, 416) = 6240

GCD(780, 416) = ( 780 x 416 ) / 6240

= 780 / 416

= 780

Step2:

LCM(52, 975) = 3900

GCD(52, 975) = ( 52 x 975 ) / 3900

= 52 / 975

= 52

Step3:

LCM(13, 154) = 2002

GCD(13, 154) = ( 13 x 154 ) / 2002

= 13 / 154

= 13

So, Greatest Common Divisor of 780, 416, 975, 154 is 1
