Given numbers are 385, 398, 665, 842
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 398) = 153230
GCD(385, 398) = ( 385 x 398 ) / 153230
= 385 / 398
= 385
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 385, 398, 665, 842 is 1
