Given numbers are 385, 145, 378, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 145) = 11165
GCD(385, 145) = ( 385 x 145 ) / 11165
= 385 / 145
= 385
Step2:
LCM(5, 378) = 1890
GCD(5, 378) = ( 5 x 378 ) / 1890
= 5 / 378
= 5
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 385, 145, 378, 404 is 1
