It is: 6
obviously, its highest common factor is the number itself. so the answer here is 90.
To find the Least Common Multiple (LCM) of 90 and 165, we first need to find the prime factorization of each number. The prime factorization of 90 is 2 x 3^2 x 5, and the prime factorization of 165 is 3 x 5 x 11. To find the LCM, we take the highest power of each prime factor that appears in either factorization: 2 x 3^2 x 5 x 11 = 990. Therefore, the LCM of 90 and 165 is 990.
90% of 165 pounds= 90% * 165= 0.9 * 165= 148.5 pounds
Common factors of 36, 72, and 90 are: 1, 2, 3, 6, 9, and 18.
