Given numbers are 665, 879, 644, 693

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 879 are 3 x 293

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 693 are 3 x 3 x 7 x 11

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

Given numbers are 665, 879, 644, 693

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

Apply this formula for all numbers.

Step1:

LCM(665, 879) = 584535

GCD(665, 879) = ( 665 x 879 ) / 584535

= 665 / 879

= 665

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

So, Greatest Common Divisor of 665, 879, 644, 693 is 1
