Given numbers are 312, 445, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(312, 445) = 138840
GCD(312, 445) = ( 312 x 445 ) / 138840
= 312 / 445
= 312
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 312, 445, 405 is 1
