The LCM of 23 and 15 is 345.
As a product of its prime factors: 3*5*23 = 345
To find the factors of 690, we start by dividing 690 by the smallest prime number, which is 2. We get 2 x 345. Continuing this process, we find the prime factorization of 690 to be 2 x 3 x 5 x 23. Therefore, the factors of 690 are 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, and 690.
345 3 x 115 3 x 5 x 23 345 = 3 x 5 x 23
3 x 5 x 23 = 345
3 x 5 x 23 = 345
1 x 345, 3 x 115, 5 x 69, 15 x 23 = 345
3 x 5 x 23 = 345
3 x 5 x 23
234 = 2 x 3 x 3 x 13 345 = 3 x 5 x 23
