Given numbers are 291, 768, 665, 975

The list of prime factors of all numbers are

Prime factors of 291 are 3 x 97

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 665 are 5 x 7 x 19

Prime factors of 975 are 3 x 5 x 5 x 13

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

Given numbers are 291, 768, 665, 975

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

Apply this formula for all numbers.

Step1:

LCM(291, 768) = 74496

GCD(291, 768) = ( 291 x 768 ) / 74496

= 291 / 768

= 291

Step2:

LCM(3, 665) = 1995

GCD(3, 665) = ( 3 x 665 ) / 1995

= 3 / 665

= 3

Step3:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

So, Greatest Common Divisor of 291, 768, 665, 975 is 1
