Given numbers are 166, 830, 310, 640

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

Apply this formula for all numbers.

Step1:

LCM(166, 830) = 830

GCD(166, 830) = ( 166 x 830 ) / 830

= 166 / 830

= 166

Step2:

LCM(166, 310) = 25730

GCD(166, 310) = ( 166 x 310 ) / 25730

= 166 / 310

= 166

Step3:

LCM(2, 640) = 640

GCD(2, 640) = ( 2 x 640 ) / 640

= 2 / 640

= 2

So, Greatest Common Divisor of 166, 830, 310, 640 is 2
