## what is the least common multiple of 4 and 8

Least common multiple of 3,6 and 7. least common multiple is common multiple for the three given numbers and should be least. let us take a. Remove the 2 x 3 that 42 and 48 have in common as prime factors. Multiply 48 by the remaining prime factors of 48 x 7 = The lowest common multiple of. As 3 and 7 are prime and the only factor of 4 (other than 1 and itself) is 2, another prime, with no common factor between three numbers. Answer and Explanation: The common multiples of 3 and 7 up to 70 are 21, 42, and A multiple of a number a is a number that is the product of a and another . Least Common Multiple of 3 and 5: List the Multiples of each number,. The multiples of 3 are 3, 6, 9, 12, 15, 18, etc. The multiples of 5 are 5, 10, 15, 20, 25, . In arithmetic and number theory, the least common multiple, lowest common multiple, . The highest power of the three prime numbers 2, 3, and 7 is 23, 32, and 71, Least common multiple = 2 × 2 × 2 × 2 × 3 × 3 × 5 = Greatest common. GRE Math Help» Arithmetic» Integers» Factors / Multiples» Least Common Therefore, our least common multiple is 2 * 3 * 52 * 7 * 11 * 19 = , This free LCM calculator determines the least common multiple of a given set of 21 = 3 × 7 14 = 2 × 7 38 = 2 × The LCM is therefore: 3 × 7 × 2 × 19 = The lowest common multiple of two integers a and b is the smallest integer than is Why the LCM of 3 consecutive numbers is a multiple of 3?
