Given numbers are 971, 400, 378, 115

The list of prime factors of all numbers are

Prime factors of 971 are 971

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 115 are 5 x 23

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

Given numbers are 971, 400, 378, 115

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

Apply this formula for all numbers.

Step1:

LCM(971, 400) = 388400

GCD(971, 400) = ( 971 x 400 ) / 388400

= 971 / 400

= 971

Step2:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 971, 400, 378, 115 is 1
