The formula, which is simpler to apply than to write out(!) is
If
X1 = pa1qb1rc1 ...
and
X2 = pa2qb2rc2 ...
where p, q, r etc are prime numbers and a, b, c etc are integers.
Then
LCM(X1, X2) = pmax(a1,a2)*qmax(b1,b2)*rmax(c1,c2) ...

Can you find the least common multiple of two prime numbers?
Yes. For two prime numbers, the LCM is their product: one times the other. Multiply the two. (e.g. LCM of 5 and 7 is 35) By formula, the LCM for x and y is LCM = x * y / GCF and for primes, the GCF (greatest common factor) is 1.
What is the LCM of 26 and 4?

What is the LCM of 45 and 54?
The LCM is: 270
What is the LCM of 56 and 98?
The LCM is 392.
What is the LCM of 15 and 2?

What is the formula LCM of 6 and 28?
84
LCM of 4 6 3?
Least Common Multiple of 454 and 463 with GCF Formula The formula of LCM is LCM (a,b) = (a × b) / GCF (a,b). We need to calculate greatest common factor 454 and 463, than apply into the LCM equation. GCF (454,463) = 1
What is the LCM of 42 63 and 105 formula?
It is: 630 by finding the prime factors of the given numbers
What is the least common multiple of 6,9?
2 * 3 = 6 3 * 3 = 9 LCM = 2 * 3 * 3 = 18 You can verify this by checking the formula: gcd(a,b) * LCM(a,b) = a * b 3 * LCM(6,9) = 54 LCM(6,9) = 18

What is the formula to find the least common multiple of first n natural numbers?
There is no exact formula. To find the sequence of LCMs see http://oeis.org/A003418/list. LCM(1, 2, 3, ..., n) tends to en as n tends to infinity. Equivalently, ln[LCM(1, 2, 3, ..., n)] tends to n or ln[LCM(1, 2, 3, ..., n)] / n tends to 1 as n tends to infinity.
