Given numbers are 820, 336, 213, 637

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 213 are 3 x 71

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 820, 336, 213, 637

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

Apply this formula for all numbers.

Step1:

LCM(820, 336) = 68880

GCD(820, 336) = ( 820 x 336 ) / 68880

= 820 / 336

= 820

Step2:

LCM(4, 213) = 852

GCD(4, 213) = ( 4 x 213 ) / 852

= 4 / 213

= 4

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 820, 336, 213, 637 is 1
