Given numbers are 408, 753, 39, 531

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

Apply this formula for all numbers.

Step1:

LCM(408, 753) = 102408

GCD(408, 753) = ( 408 x 753 ) / 102408

= 408 / 753

= 408

Step2:

LCM(3, 39) = 39

GCD(3, 39) = ( 3 x 39 ) / 39

= 3 / 39

= 3

Step3:

LCM(3, 531) = 531

GCD(3, 531) = ( 3 x 531 ) / 531

= 3 / 531

= 3

So, Greatest Common Divisor of 408, 753, 39, 531 is 3
