Given numbers are 390, 342, 173, 918
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 342) = 22230
GCD(390, 342) = ( 390 x 342 ) / 22230
= 390 / 342
= 390
Step2:
LCM(6, 173) = 1038
GCD(6, 173) = ( 6 x 173 ) / 1038
= 6 / 173
= 6
Step3:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
So, Greatest Common Divisor of 390, 342, 173, 918 is 1
