Given numbers are 783, 840, 453

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

Apply this formula for all numbers.

Step1:

LCM(783, 840) = 219240

GCD(783, 840) = ( 783 x 840 ) / 219240

= 783 / 840

= 783

Step2:

LCM(3, 453) = 453

GCD(3, 453) = ( 3 x 453 ) / 453

= 3 / 453

= 3

So, Greatest Common Divisor of 783, 840, 453 is 3
