Given numbers are 407, 952, 646, 920

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 952 are 2 x 2 x 2 x 7 x 17

Prime factors of 646 are 2 x 17 x 19

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 407, 952, 646, 920

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

Apply this formula for all numbers.

Step1:

LCM(407, 952) = 387464

GCD(407, 952) = ( 407 x 952 ) / 387464

= 407 / 952

= 407

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 407, 952, 646, 920 is 1
