Given numbers are 131, 205, 644

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

Apply this formula for all numbers.

Step1:

LCM(131, 205) = 26855

GCD(131, 205) = ( 131 x 205 ) / 26855

= 131 / 205

= 131

Step2:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 131, 205, 644 is 1
