Given numbers are 155, 878, 288, 130

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 878 are 2 x 439

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 155, 878, 288, 130

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

Apply this formula for all numbers.

Step1:

LCM(155, 878) = 136090

GCD(155, 878) = ( 155 x 878 ) / 136090

= 155 / 878

= 155

Step2:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 155, 878, 288, 130 is 1
