Given numbers are 720, 672, 493, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 672) = 10080
GCD(720, 672) = ( 720 x 672 ) / 10080
= 720 / 672
= 720
Step2:
LCM(48, 493) = 23664
GCD(48, 493) = ( 48 x 493 ) / 23664
= 48 / 493
= 48
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 720, 672, 493, 789 is 1
