Given numbers are 644, 289, 185

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

Apply this formula for all numbers.

Step1:

LCM(644, 289) = 186116

GCD(644, 289) = ( 644 x 289 ) / 186116

= 644 / 289

= 644

Step2:

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

= 1 / 185

= 1

So, Greatest Common Divisor of 644, 289, 185 is 1
