Given numbers are 166, 155, 425, 860

The list of prime factors of all numbers are

Prime factors of 166 are 2 x 83

Prime factors of 155 are 5 x 31

Prime factors of 425 are 5 x 5 x 17

Prime factors of 860 are 2 x 2 x 5 x 43

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

Given numbers are 166, 155, 425, 860

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

Apply this formula for all numbers.

Step1:

LCM(166, 155) = 25730

GCD(166, 155) = ( 166 x 155 ) / 25730

= 166 / 155

= 166

Step2:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 166, 155, 425, 860 is 1
