Given numbers are 637, 821, 858, 748

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 821 are 821

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

Prime factors of 748 are 2 x 2 x 11 x 17

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

Given numbers are 637, 821, 858, 748

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

Apply this formula for all numbers.

Step1:

LCM(637, 821) = 522977

GCD(637, 821) = ( 637 x 821 ) / 522977

= 637 / 821

= 637

Step2:

LCM(1, 858) = 858

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

= 1 / 858

= 1

Step3:

LCM(1, 748) = 748

GCD(1, 748) = ( 1 x 748 ) / 748

= 1 / 748

= 1

So, Greatest Common Divisor of 637, 821, 858, 748 is 1
