Given numbers are 162, 546, 130, 861

The list of prime factors of all numbers are

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

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 130 are 2 x 5 x 13

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 162, 546, 130, 861

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

Apply this formula for all numbers.

Step1:

LCM(162, 546) = 14742

GCD(162, 546) = ( 162 x 546 ) / 14742

= 162 / 546

= 162

Step2:

LCM(6, 130) = 390

GCD(6, 130) = ( 6 x 130 ) / 390

= 6 / 130

= 6

Step3:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

So, Greatest Common Divisor of 162, 546, 130, 861 is 1
