Given numbers are 649, 556, 31

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

Apply this formula for all numbers.

Step1:

LCM(649, 556) = 360844

GCD(649, 556) = ( 649 x 556 ) / 360844

= 649 / 556

= 649

Step2:

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

= 1 / 31

= 1

So, Greatest Common Divisor of 649, 556, 31 is 1
