Given numbers are 217, 654, 668

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

Apply this formula for all numbers.

Step1:

LCM(217, 654) = 141918

GCD(217, 654) = ( 217 x 654 ) / 141918

= 217 / 654

= 217

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 217, 654, 668 is 1
