216 divided by 54 equals 4
To get to the factors of 216, one should start by dividing by prime numbers until there are no longer any that are divisible. Since 216 is even, we will start with 2 as follows: 216 / 2 = 108 108 / 2 = 54 54 / 2 = 27 27 is no longer divisible by two, so we will move into higher prime numbers as follows: 27 / 3 = 9 9 / 3 = 3 We have reduced 216 to primes using the following prime factorization: 2 * 2 * 2 * 3 * 3 *3 or 23 * 33 The factors of 216 are then computed by taking all of the combination of the prime factorization plus 1 as follows: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
The LCM of 54 and 72 is 216, which is the multiple of the highest power of prime factors from both numbers (23 x 33 = 2 x 2 x 2 x 3 x 3 x 3 = 216). (Prime factors: 54 = 2 x 33; 72 = 23 x 32)
