GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 394) = 336870
GCD(855, 394) = ( 855 x 394 ) / 336870
= 855 / 394
= 855
Step2:
LCM(1, 896) = 896
GCD(1, 896) = ( 1 x 896 ) / 896
= 1 / 896
= 1
Step3:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
So, Greatest Common Divisor of 855, 394, 896, 170 is 1
