Enter positive integers:LCM of 7 and 9 is 63. The LCM of any two integers in mathematics is the value that is evenly divisible by the two values. Among all common multiples of 7 and 9, the LCM of 7 and 9 is the smallest number. (7, 14, 21, 28, 35, 42,…) and (9, 18, 27, 36, 45,…) are the first few multiples of 7 and 9.Mar 4, 2023 ... The least common multiple of 3, 5, 7 and 9 is 315. mark me brainliest plssss.Prime factors of 5 are 5. Prime factorization of 5 in exponent form is: 5 = 5 1. Step 2: Multiply together each of the Prime Numbers with the highest power to obtain the Least Common Multiple. On doing so, you will get the resultant equation as 5 1 ×7 1 = 35. Therefore, LCM of two numbers 7 and 5 is 35. LCM (7,5) = 35.Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2. By the same principle, 10 is the least common multiple of −5 and −2 as well. Notation. The least common multiple of two integers a and b is denoted as lcm(a, b). Some older textbooks use [a, b].
