Given numbers are 756, 764, 605, 155

The list of prime factors of all numbers are

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

Prime factors of 764 are 2 x 2 x 191

Prime factors of 605 are 5 x 11 x 11

Prime factors of 155 are 5 x 31

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

Given numbers are 756, 764, 605, 155

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

Apply this formula for all numbers.

Step1:

LCM(756, 764) = 144396

GCD(756, 764) = ( 756 x 764 ) / 144396

= 756 / 764

= 756

Step2:

LCM(4, 605) = 2420

GCD(4, 605) = ( 4 x 605 ) / 2420

= 4 / 605

= 4

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 756, 764, 605, 155 is 1
