Given numbers are 646, 754, 977, 650

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 754 are 2 x 13 x 29

Prime factors of 977 are 977

Prime factors of 650 are 2 x 5 x 5 x 13

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

Given numbers are 646, 754, 977, 650

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

Apply this formula for all numbers.

Step1:

LCM(646, 754) = 243542

GCD(646, 754) = ( 646 x 754 ) / 243542

= 646 / 754

= 646

Step2:

LCM(2, 977) = 1954

GCD(2, 977) = ( 2 x 977 ) / 1954

= 2 / 977

= 2

Step3:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

So, Greatest Common Divisor of 646, 754, 977, 650 is 1
