Given numbers are 840, 702, 519, 831

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

Apply this formula for all numbers.

Step1:

LCM(840, 702) = 98280

GCD(840, 702) = ( 840 x 702 ) / 98280

= 840 / 702

= 840

Step2:

LCM(6, 519) = 1038

GCD(6, 519) = ( 6 x 519 ) / 1038

= 6 / 519

= 6

Step3:

LCM(3, 831) = 831

GCD(3, 831) = ( 3 x 831 ) / 831

= 3 / 831

= 3

So, Greatest Common Divisor of 840, 702, 519, 831 is 3
