Given numbers are 223, 275, 644

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

Apply this formula for all numbers.

Step1:

LCM(223, 275) = 61325

GCD(223, 275) = ( 223 x 275 ) / 61325

= 223 / 275

= 223

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 223, 275, 644 is 1
