Given numbers are 135, 420, 145, 878

The list of prime factors of all numbers are

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 145 are 5 x 29

Prime factors of 878 are 2 x 439

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

Given numbers are 135, 420, 145, 878

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

Apply this formula for all numbers.

Step1:

LCM(135, 420) = 3780

GCD(135, 420) = ( 135 x 420 ) / 3780

= 135 / 420

= 135

Step2:

LCM(15, 145) = 435

GCD(15, 145) = ( 15 x 145 ) / 435

= 15 / 145

= 15

Step3:

LCM(5, 878) = 4390

GCD(5, 878) = ( 5 x 878 ) / 4390

= 5 / 878

= 5

So, Greatest Common Divisor of 135, 420, 145, 878 is 1
