GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 855) = 118845
GCD(417, 855) = ( 417 x 855 ) / 118845
= 417 / 855
= 417
Step2:
LCM(3, 987) = 987
GCD(3, 987) = ( 3 x 987 ) / 987
= 3 / 987
= 3
Step3:
LCM(3, 174) = 174
GCD(3, 174) = ( 3 x 174 ) / 174
= 3 / 174
= 3
So, Greatest Common Divisor of 417, 855, 987, 174 is 3
