3x3x3x5 are prime factors of the number 135
2 x 3 x 5 = 30 3 x 3 x 3 x 5 = 135
To find the Least Common Multiple (LCM) of three numbers, you first need to find the prime factorization of each number. The prime factorization of 108 is 2^2 * 3^3, the prime factorization of 135 is 3^3 * 5, and the prime factorization of 162 is 2 * 3^4. Then, you take the highest power of each prime factor that appears in any of the factorizations, which gives you 2^2 * 3^4 * 5 = 540. Therefore, the LCM of 108, 135, and 162 is 540.
The prime factorization is... 2x2x2x2x2x5x5
To find the greatest common factor of a set of numbers, do a prime factorization of each one, then multiply the prime factors that the numbers have in common. The prime factorization of 54 is: 2 x 3 x 3 x 3 The prime factorization of 81 is: 3 x 3 x 3 x 3 The prime factorization of 135 is: 3 x 3 x 3 x 5 All three numbers have three 3's in common as prime factors, so the GCF of all three numbers is: 3 x 3 x 3 = 27.
