Given numbers are 640, 166, 681, 218

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

Apply this formula for all numbers.

Step1:

LCM(640, 166) = 53120

GCD(640, 166) = ( 640 x 166 ) / 53120

= 640 / 166

= 640

Step2:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 640, 166, 681, 218 is 1
