Given numbers are 858, 368, 220, 665

The list of prime factors of all numbers are

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

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 858, 368, 220, 665

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

Apply this formula for all numbers.

Step1:

LCM(858, 368) = 157872

GCD(858, 368) = ( 858 x 368 ) / 157872

= 858 / 368

= 858

Step2:

LCM(2, 220) = 220

GCD(2, 220) = ( 2 x 220 ) / 220

= 2 / 220

= 2

Step3:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

So, Greatest Common Divisor of 858, 368, 220, 665 is 1
