Given numbers are 858, 407, 744, 180

The list of prime factors of all numbers are

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 407 are 11 x 37

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 858, 407, 744, 180

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

Apply this formula for all numbers.

Step1:

LCM(858, 407) = 31746

GCD(858, 407) = ( 858 x 407 ) / 31746

= 858 / 407

= 858

Step2:

LCM(11, 744) = 8184

GCD(11, 744) = ( 11 x 744 ) / 8184

= 11 / 744

= 11

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 858, 407, 744, 180 is 1
