Given numbers are 644, 360, 190, 744

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

Apply this formula for all numbers.

Step1:

LCM(644, 360) = 57960

GCD(644, 360) = ( 644 x 360 ) / 57960

= 644 / 360

= 644

Step2:

LCM(4, 190) = 380

GCD(4, 190) = ( 4 x 190 ) / 380

= 4 / 190

= 4

Step3:

LCM(2, 744) = 744

GCD(2, 744) = ( 2 x 744 ) / 744

= 2 / 744

= 2

So, Greatest Common Divisor of 644, 360, 190, 744 is 2
