Given numbers are 505, 307, 912, 400

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 307 are 307

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

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

Given numbers are 505, 307, 912, 400

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

Apply this formula for all numbers.

Step1:

LCM(505, 307) = 155035

GCD(505, 307) = ( 505 x 307 ) / 155035

= 505 / 307

= 505

Step2:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 505, 307, 912, 400 is 1
