Given numbers are 905, 148, 756, 665

The list of prime factors of all numbers are

Prime factors of 905 are 5 x 181

Prime factors of 148 are 2 x 2 x 37

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 905, 148, 756, 665

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

Apply this formula for all numbers.

Step1:

LCM(905, 148) = 133940

GCD(905, 148) = ( 905 x 148 ) / 133940

= 905 / 148

= 905

Step2:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 905, 148, 756, 665 is 1
