Given numbers are 471, 406, 858, 640

The list of prime factors of all numbers are

Prime factors of 471 are 3 x 157

Prime factors of 406 are 2 x 7 x 29

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

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 471, 406, 858, 640

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

Apply this formula for all numbers.

Step1:

LCM(471, 406) = 191226

GCD(471, 406) = ( 471 x 406 ) / 191226

= 471 / 406

= 471

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 640) = 640

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

= 1 / 640

= 1

So, Greatest Common Divisor of 471, 406, 858, 640 is 1
