Given numbers are 820, 995, 139, 161

The list of prime factors of all numbers are

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

Prime factors of 995 are 5 x 199

Prime factors of 139 are 139

Prime factors of 161 are 7 x 23

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

Given numbers are 820, 995, 139, 161

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

Apply this formula for all numbers.

Step1:

LCM(820, 995) = 163180

GCD(820, 995) = ( 820 x 995 ) / 163180

= 820 / 995

= 820

Step2:

LCM(5, 139) = 695

GCD(5, 139) = ( 5 x 139 ) / 695

= 5 / 139

= 5

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 820, 995, 139, 161 is 1
