Given numbers are 732, 855, 840

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

Apply this formula for all numbers.

Step1:

LCM(732, 855) = 208620

GCD(732, 855) = ( 732 x 855 ) / 208620

= 732 / 855

= 732

Step2:

LCM(3, 840) = 840

GCD(3, 840) = ( 3 x 840 ) / 840

= 3 / 840

= 3

So, Greatest Common Divisor of 732, 855, 840 is 3
