Given numbers are 166, 104, 640, 787

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

Apply this formula for all numbers.

Step1:

LCM(166, 104) = 8632

GCD(166, 104) = ( 166 x 104 ) / 8632

= 166 / 104

= 166

Step2:

LCM(2, 640) = 640

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

= 2 / 640

= 2

Step3:

LCM(2, 787) = 1574

GCD(2, 787) = ( 2 x 787 ) / 1574

= 2 / 787

= 2

So, Greatest Common Divisor of 166, 104, 640, 787 is 1
