Given numbers are 644, 310, 824, 475

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

Apply this formula for all numbers.

Step1:

LCM(644, 310) = 99820

GCD(644, 310) = ( 644 x 310 ) / 99820

= 644 / 310

= 644

Step2:

LCM(2, 824) = 824

GCD(2, 824) = ( 2 x 824 ) / 824

= 2 / 824

= 2

Step3:

LCM(2, 475) = 950

GCD(2, 475) = ( 2 x 475 ) / 950

= 2 / 475

= 2

So, Greatest Common Divisor of 644, 310, 824, 475 is 1
