Given numbers are 385, 865, 842, 342
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 865) = 66605
GCD(385, 865) = ( 385 x 865 ) / 66605
= 385 / 865
= 385
Step2:
LCM(5, 842) = 4210
GCD(5, 842) = ( 5 x 842 ) / 4210
= 5 / 842
= 5
Step3:
LCM(1, 342) = 342
GCD(1, 342) = ( 1 x 342 ) / 342
= 1 / 342
= 1
So, Greatest Common Divisor of 385, 865, 842, 342 is 1
