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

Apply this formula for all numbers.

Step1:

LCM(688, 824) = 70864

GCD(688, 824) = ( 688 x 824 ) / 70864

= 688 / 824

= 688

Step2:

LCM(8, 222) = 888

GCD(8, 222) = ( 8 x 222 ) / 888

= 8 / 222

= 8

Step3:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

So, Greatest Common Divisor of 688, 824, 222, 668 is 2
