Given numbers are 405, 280, 463, 443
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 280) = 22680
GCD(405, 280) = ( 405 x 280 ) / 22680
= 405 / 280
= 405
Step2:
LCM(5, 463) = 2315
GCD(5, 463) = ( 5 x 463 ) / 2315
= 5 / 463
= 5
Step3:
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
= 1 / 443
= 1
So, Greatest Common Divisor of 405, 280, 463, 443 is 1
