Given numbers are 210, 730, 761, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 730) = 15330
GCD(210, 730) = ( 210 x 730 ) / 15330
= 210 / 730
= 210
Step2:
LCM(10, 761) = 7610
GCD(10, 761) = ( 10 x 761 ) / 7610
= 10 / 761
= 10
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 210, 730, 761, 789 is 1
