Given numbers are 810, 618, 657, 142

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 618 are 2 x 3 x 103

Prime factors of 657 are 3 x 3 x 73

Prime factors of 142 are 2 x 71

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

Given numbers are 810, 618, 657, 142

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

Apply this formula for all numbers.

Step1:

LCM(810, 618) = 83430

GCD(810, 618) = ( 810 x 618 ) / 83430

= 810 / 618

= 810

Step2:

LCM(6, 657) = 1314

GCD(6, 657) = ( 6 x 657 ) / 1314

= 6 / 657

= 6

Step3:

LCM(3, 142) = 426

GCD(3, 142) = ( 3 x 142 ) / 426

= 3 / 142

= 3

So, Greatest Common Divisor of 810, 618, 657, 142 is 1
