Given numbers are 861, 360, 147, 325

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 147 are 3 x 7 x 7

Prime factors of 325 are 5 x 5 x 13

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

Given numbers are 861, 360, 147, 325

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

Apply this formula for all numbers.

Step1:

LCM(861, 360) = 103320

GCD(861, 360) = ( 861 x 360 ) / 103320

= 861 / 360

= 861

Step2:

LCM(3, 147) = 147

GCD(3, 147) = ( 3 x 147 ) / 147

= 3 / 147

= 3

Step3:

LCM(3, 325) = 975

GCD(3, 325) = ( 3 x 325 ) / 975

= 3 / 325

= 3

So, Greatest Common Divisor of 861, 360, 147, 325 is 1
