Given numbers are 840, 322, 721, 702
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 322) = 19320
GCD(840, 322) = ( 840 x 322 ) / 19320
= 840 / 322
= 840
Step2:
LCM(14, 721) = 1442
GCD(14, 721) = ( 14 x 721 ) / 1442
= 14 / 721
= 14
Step3:
LCM(7, 702) = 4914
GCD(7, 702) = ( 7 x 702 ) / 4914
= 7 / 702
= 7
So, Greatest Common Divisor of 840, 322, 721, 702 is 1
