Given numbers are 144, 138, 151, 155

The list of prime factors of all numbers are

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 138 are 2 x 3 x 23

Prime factors of 151 are 151

Prime factors of 155 are 5 x 31

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

Given numbers are 144, 138, 151, 155

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

Apply this formula for all numbers.

Step1:

LCM(144, 138) = 3312

GCD(144, 138) = ( 144 x 138 ) / 3312

= 144 / 138

= 144

Step2:

LCM(6, 151) = 906

GCD(6, 151) = ( 6 x 151 ) / 906

= 6 / 151

= 6

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 144, 138, 151, 155 is 1
