Given numbers are 644, 395, 127

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

Apply this formula for all numbers.

Step1:

LCM(644, 395) = 254380

GCD(644, 395) = ( 644 x 395 ) / 254380

= 644 / 395

= 644

Step2:

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

= 1 / 127

= 1

So, Greatest Common Divisor of 644, 395, 127 is 1
