Given numbers are 220, 686, 662, 326

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

Apply this formula for all numbers.

Step1:

LCM(220, 686) = 75460

GCD(220, 686) = ( 220 x 686 ) / 75460

= 220 / 686

= 220

Step2:

LCM(2, 662) = 662

GCD(2, 662) = ( 2 x 662 ) / 662

= 2 / 662

= 2

Step3:

LCM(2, 326) = 326

GCD(2, 326) = ( 2 x 326 ) / 326

= 2 / 326

= 2

So, Greatest Common Divisor of 220, 686, 662, 326 is 2
