Given numbers are 140, 800, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 800) = 5600
GCD(140, 800) = ( 140 x 800 ) / 5600
= 140 / 800
= 140
Step2:
LCM(20, 640) = 640
GCD(20, 640) = ( 20 x 640 ) / 640
= 20 / 640
= 20
So, Greatest Common Divisor of 140, 800, 640 is 20
