Given numbers are 831, 732, 279, 648
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 732) = 202764
GCD(831, 732) = ( 831 x 732 ) / 202764
= 831 / 732
= 831
Step2:
LCM(3, 279) = 279
GCD(3, 279) = ( 3 x 279 ) / 279
= 3 / 279
= 3
Step3:
LCM(3, 648) = 648
GCD(3, 648) = ( 3 x 648 ) / 648
= 3 / 648
= 3
So, Greatest Common Divisor of 831, 732, 279, 648 is 3
