Given numbers are 730, 210, 695, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(730, 210) = 15330
GCD(730, 210) = ( 730 x 210 ) / 15330
= 730 / 210
= 730
Step2:
LCM(10, 695) = 1390
GCD(10, 695) = ( 10 x 695 ) / 1390
= 10 / 695
= 10
Step3:
LCM(5, 210) = 210
GCD(5, 210) = ( 5 x 210 ) / 210
= 5 / 210
= 5
So, Greatest Common Divisor of 730, 210, 695, 210 is 5
