Given numbers are 385, 493, 161, 281
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 493) = 189805
GCD(385, 493) = ( 385 x 493 ) / 189805
= 385 / 493
= 385
Step2:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
Step3:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
So, Greatest Common Divisor of 385, 493, 161, 281 is 1
