Given numbers are 115, 387, 435, 945

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 387 are 3 x 3 x 43

Prime factors of 435 are 3 x 5 x 29

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 115, 387, 435, 945

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

Apply this formula for all numbers.

Step1:

LCM(115, 387) = 44505

GCD(115, 387) = ( 115 x 387 ) / 44505

= 115 / 387

= 115

Step2:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 115, 387, 435, 945 is 1
