Given numbers are 644, 406, 24, 849

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

Apply this formula for all numbers.

Step1:

LCM(644, 406) = 18676

GCD(644, 406) = ( 644 x 406 ) / 18676

= 644 / 406

= 644

Step2:

LCM(14, 24) = 168

GCD(14, 24) = ( 14 x 24 ) / 168

= 14 / 24

= 14

Step3:

LCM(2, 849) = 1698

GCD(2, 849) = ( 2 x 849 ) / 1698

= 2 / 849

= 2

So, Greatest Common Divisor of 644, 406, 24, 849 is 1
