Given numbers are 223, 645, 138

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

Apply this formula for all numbers.

Step1:

LCM(223, 645) = 143835

GCD(223, 645) = ( 223 x 645 ) / 143835

= 223 / 645

= 223

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 223, 645, 138 is 1
