Given numbers are 385, 640, 185, 997
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 640) = 49280
GCD(385, 640) = ( 385 x 640 ) / 49280
= 385 / 640
= 385
Step2:
LCM(5, 185) = 185
GCD(5, 185) = ( 5 x 185 ) / 185
= 5 / 185
= 5
Step3:
LCM(5, 997) = 4985
GCD(5, 997) = ( 5 x 997 ) / 4985
= 5 / 997
= 5
So, Greatest Common Divisor of 385, 640, 185, 997 is 1
