Given numbers are 681, 820, 220, 162

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

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

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

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

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

Given numbers are 681, 820, 220, 162

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

Apply this formula for all numbers.

Step1:

LCM(681, 820) = 558420

GCD(681, 820) = ( 681 x 820 ) / 558420

= 681 / 820

= 681

Step2:

LCM(1, 220) = 220

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

= 1 / 220

= 1

Step3:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 681, 820, 220, 162 is 1
