Given numbers are 705, 120, 800
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 120) = 5640
GCD(705, 120) = ( 705 x 120 ) / 5640
= 705 / 120
= 705
Step2:
LCM(15, 800) = 2400
GCD(15, 800) = ( 15 x 800 ) / 2400
= 15 / 800
= 15
So, Greatest Common Divisor of 705, 120, 800 is 5
