A least common multiple of a and b is a common multiple that is minimal, in the sense that for any other common multiple n of a and b, m divides n. In general, two elements in a commutative ring can have no least common multiple or more than one. However, any two least common multiples of the same pair of elements are associates. [10]

Here, 36 is the least common multiple of 12 and 18. Their product, 216, is also a common denominator, but calculating with that denominator involves larger numbers:
lcm(m, n) (least common multiple of m and n) is the product of all prime factors of m or n (with the largest multiplicity for m or n). gcd(m, n) × lcm(m, n) = m × n. Finding the prime factors is often harder than computing gcd and lcm using other algorithms which do not require known prime factorization.

The Carmichael lambda function of a prime power can be expressed in terms of the Euler totient. Any number that is not 1 or a prime power can be written uniquely as the product of distinct prime powers, in which case λ of the product is the least common multiple of the λ of the prime power factors.
[f] ^ For the SCM women's 200 free American Record, Allison Schmitt swam a faster time at the 2009 Duel in the Pool (1:51.67); however, the time has not been recognized as a record by USA Swimming. [g] ^ For the SCM women's 400 IM American Record , Julia Smit at the 2009 Duel in the Pool set a then-World Record of 4:21.04; however, this time ...
Lure coursing is a sport for dogs that involves chasing a mechanically operated lure. Competition is typically limited to dogs of purebred sighthound breeds. The AKC has a pass/fail trial for all breeds called the Coursing Ability Test (CAT) and a timed 100 yard dash called Fast CAT where the dog's speed is converted to points.
