Using only positive integers:
6 x 9
It is: 8 times 15 = 120
40% of 120 is same as 40/100 times 120 = 48
The factor pairs of 66 are: 1 × 66 2 × 33 3 × 22 6 × 11
The least common multiple (LCM) of 90 and 120 can be found by determining the prime factorization of each number. The prime factorization of 90 is (2^1 \times 3^2 \times 5^1), and for 120, it is (2^3 \times 3^1 \times 5^1). To find the LCM, take the highest power of each prime: (2^3), (3^2), and (5^1). Thus, the LCM is (2^3 \times 3^2 \times 5^1 = 360).
