GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(800, 128) = 3200
GCD(800, 128) = ( 800 x 128 ) / 3200
= 800 / 128
= 800
Step2:
LCM(32, 860) = 6880
GCD(32, 860) = ( 32 x 860 ) / 6880
= 32 / 860
= 32
So, Greatest Common Divisor of 800, 128, 860 is 4
