Given numbers are 622, 451, 220, 858

The list of prime factors of all numbers are

Prime factors of 622 are 2 x 311

Prime factors of 451 are 11 x 41

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

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

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

Given numbers are 622, 451, 220, 858

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

Apply this formula for all numbers.

Step1:

LCM(622, 451) = 280522

GCD(622, 451) = ( 622 x 451 ) / 280522

= 622 / 451

= 622

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 622, 451, 220, 858 is 1
