Given numbers are 820, 356, 520, 681

The list of prime factors of all numbers are

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

Prime factors of 356 are 2 x 2 x 89

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 681 are 3 x 227

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

Given numbers are 820, 356, 520, 681

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

Apply this formula for all numbers.

Step1:

LCM(820, 356) = 72980

GCD(820, 356) = ( 820 x 356 ) / 72980

= 820 / 356

= 820

Step2:

LCM(4, 520) = 520

GCD(4, 520) = ( 4 x 520 ) / 520

= 4 / 520

= 4

Step3:

LCM(4, 681) = 2724

GCD(4, 681) = ( 4 x 681 ) / 2724

= 4 / 681

= 4

So, Greatest Common Divisor of 820, 356, 520, 681 is 1
