Given numbers are 774, 744, 160, 645

The list of prime factors of all numbers are

Prime factors of 774 are 2 x 3 x 3 x 43

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 774, 744, 160, 645

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

Apply this formula for all numbers.

Step1:

LCM(774, 744) = 95976

GCD(774, 744) = ( 774 x 744 ) / 95976

= 774 / 744

= 774

Step2:

LCM(6, 160) = 480

GCD(6, 160) = ( 6 x 160 ) / 480

= 6 / 160

= 6

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 774, 744, 160, 645 is 1
