Given numbers are 861, 432, 130, 134

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 130 are 2 x 5 x 13

Prime factors of 134 are 2 x 67

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

Given numbers are 861, 432, 130, 134

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

Apply this formula for all numbers.

Step1:

LCM(861, 432) = 123984

GCD(861, 432) = ( 861 x 432 ) / 123984

= 861 / 432

= 861

Step2:

LCM(3, 130) = 390

GCD(3, 130) = ( 3 x 130 ) / 390

= 3 / 130

= 3

Step3:

LCM(1, 134) = 134

GCD(1, 134) = ( 1 x 134 ) / 134

= 1 / 134

= 1

So, Greatest Common Divisor of 861, 432, 130, 134 is 1
