Given numbers are 720, 422, 835
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 422) = 151920
GCD(720, 422) = ( 720 x 422 ) / 151920
= 720 / 422
= 720
Step2:
LCM(2, 835) = 1670
GCD(2, 835) = ( 2 x 835 ) / 1670
= 2 / 835
= 2
So, Greatest Common Divisor of 720, 422, 835 is 1
