Given numbers are 832, 140, 644

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

Apply this formula for all numbers.

Step1:

LCM(832, 140) = 29120

GCD(832, 140) = ( 832 x 140 ) / 29120

= 832 / 140

= 832

Step2:

LCM(4, 644) = 644

GCD(4, 644) = ( 4 x 644 ) / 644

= 4 / 644

= 4

So, Greatest Common Divisor of 832, 140, 644 is 4
