Given numbers are 621, 460, 143, 858

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 143 are 11 x 13

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 621, 460, 143, 858

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

Apply this formula for all numbers.

Step1:

LCM(621, 460) = 12420

GCD(621, 460) = ( 621 x 460 ) / 12420

= 621 / 460

= 621

Step2:

LCM(23, 143) = 3289

GCD(23, 143) = ( 23 x 143 ) / 3289

= 23 / 143

= 23

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 621, 460, 143, 858 is 1
