Given numbers are 855, 270, 646, 749

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 646 are 2 x 17 x 19

Prime factors of 749 are 7 x 107

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

Given numbers are 855, 270, 646, 749

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

Apply this formula for all numbers.

Step1:

LCM(855, 270) = 5130

GCD(855, 270) = ( 855 x 270 ) / 5130

= 855 / 270

= 855

Step2:

LCM(45, 646) = 29070

GCD(45, 646) = ( 45 x 646 ) / 29070

= 45 / 646

= 45

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 855, 270, 646, 749 is 1
