Given numbers are 387, 143, 156

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 143 are 11 x 13

Prime factors of 156 are 2 x 2 x 3 x 13

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

Given numbers are 387, 143, 156

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

Apply this formula for all numbers.

Step1:

LCM(387, 143) = 55341

GCD(387, 143) = ( 387 x 143 ) / 55341

= 387 / 143

= 387

Step2:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 387, 143, 156 is 1
