Given numbers are 166, 840, 75, 180

The list of prime factors of all numbers are

Prime factors of 166 are 2 x 83

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 75 are 3 x 5 x 5

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 166, 840, 75, 180

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

Apply this formula for all numbers.

Step1:

LCM(166, 840) = 69720

GCD(166, 840) = ( 166 x 840 ) / 69720

= 166 / 840

= 166

Step2:

LCM(2, 75) = 150

GCD(2, 75) = ( 2 x 75 ) / 150

= 2 / 75

= 2

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 166, 840, 75, 180 is 1
