Given numbers are 830, 120, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 120) = 9960
GCD(830, 120) = ( 830 x 120 ) / 9960
= 830 / 120
= 830
Step2:
LCM(10, 643) = 6430
GCD(10, 643) = ( 10 x 643 ) / 6430
= 10 / 643
= 10
So, Greatest Common Divisor of 830, 120, 643 is 1
