Given numbers are 140, 210, 879
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 210) = 420
GCD(140, 210) = ( 140 x 210 ) / 420
= 140 / 210
= 140
Step2:
LCM(70, 879) = 61530
GCD(70, 879) = ( 70 x 879 ) / 61530
= 70 / 879
= 70
So, Greatest Common Divisor of 140, 210, 879 is 1
