Given numbers are 254, 720, 870, 149

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 149 are 149

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

Given numbers are 254, 720, 870, 149

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

Apply this formula for all numbers.

Step1:

LCM(254, 720) = 91440

GCD(254, 720) = ( 254 x 720 ) / 91440

= 254 / 720

= 254

Step2:

LCM(2, 870) = 870

GCD(2, 870) = ( 2 x 870 ) / 870

= 2 / 870

= 2

Step3:

LCM(2, 149) = 298

GCD(2, 149) = ( 2 x 149 ) / 298

= 2 / 149

= 2

So, Greatest Common Divisor of 254, 720, 870, 149 is 1
