Given numbers are 147, 440, 391, 151

The list of prime factors of all numbers are

Prime factors of 147 are 3 x 7 x 7

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 391 are 17 x 23

Prime factors of 151 are 151

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

Given numbers are 147, 440, 391, 151

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

Apply this formula for all numbers.

Step1:

LCM(147, 440) = 64680

GCD(147, 440) = ( 147 x 440 ) / 64680

= 147 / 440

= 147

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 151) = 151

GCD(1, 151) = ( 1 x 151 ) / 151

= 1 / 151

= 1

So, Greatest Common Divisor of 147, 440, 391, 151 is 1
