Given numbers are 864, 220, 634, 666

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

Apply this formula for all numbers.

Step1:

LCM(864, 220) = 47520

GCD(864, 220) = ( 864 x 220 ) / 47520

= 864 / 220

= 864

Step2:

LCM(4, 634) = 1268

GCD(4, 634) = ( 4 x 634 ) / 1268

= 4 / 634

= 4

Step3:

LCM(2, 666) = 666

GCD(2, 666) = ( 2 x 666 ) / 666

= 2 / 666

= 2

So, Greatest Common Divisor of 864, 220, 634, 666 is 2
