Given numbers are 297, 720, 890, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 720) = 23760
GCD(297, 720) = ( 297 x 720 ) / 23760
= 297 / 720
= 297
Step2:
LCM(9, 890) = 8010
GCD(9, 890) = ( 9 x 890 ) / 8010
= 9 / 890
= 9
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 297, 720, 890, 789 is 1
