Given numbers are 387, 359, 800, 660

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 359 are 359

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 387, 359, 800, 660

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

Apply this formula for all numbers.

Step1:

LCM(387, 359) = 138933

GCD(387, 359) = ( 387 x 359 ) / 138933

= 387 / 359

= 387

Step2:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 387, 359, 800, 660 is 1
