Given numbers are 384, 165, 162, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(384, 165) = 21120
GCD(384, 165) = ( 384 x 165 ) / 21120
= 384 / 165
= 384
Step2:
LCM(3, 162) = 162
GCD(3, 162) = ( 3 x 162 ) / 162
= 3 / 162
= 3
Step3:
LCM(3, 445) = 1335
GCD(3, 445) = ( 3 x 445 ) / 1335
= 3 / 445
= 3
So, Greatest Common Divisor of 384, 165, 162, 445 is 1
