Given numbers are 120, 775, 668, 810

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 775 are 5 x 5 x 31

Prime factors of 668 are 2 x 2 x 167

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

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

Given numbers are 120, 775, 668, 810

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

Apply this formula for all numbers.

Step1:

LCM(120, 775) = 18600

GCD(120, 775) = ( 120 x 775 ) / 18600

= 120 / 775

= 120

Step2:

LCM(5, 668) = 3340

GCD(5, 668) = ( 5 x 668 ) / 3340

= 5 / 668

= 5

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 120, 775, 668, 810 is 1
