The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCF of 405 and 486, we can use the prime factorization method. First, we find the prime factors of both numbers: 405 = 3 x 3 x 3 x 3 x 5 and 486 = 2 x 3 x 3 x 3 x 3 x 3. Then, we identify the common prime factors, which are 3 x 3 x 3 = 27. Therefore, the GCF of 405 and 486 is 27.
The GCF is 6.
405 times
First take the '5' in '65'. The number '81' times '5' gives you '405'. Then take the '6' in '65'. The number '81' times '6' gives you '486'.Now add '405' and '486'. But you'll be shifting the '486' one place over to the left. So starting from the right on the upper adding line, the '5' from '405' has nothing to be added together with. So the result is '5'.Go to the '0' in '405'. It needs to be added with the '6' of '486'. That gives you '6'.Go to the '4' in '405'. It needs to be added with the '8' of '486'. That gives you '12'. Keep the '2' of '12', but carry the '1' over to the left.There's nothing left from the adding line that has '405'. But you still have the '4' of '486' on the lower adding line. So you add the '1' of '12' to the '4' of '486'. That gives you '5'.So your total is 5,265.
