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) ...

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 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 LCM of 9 and 32?

The Least Common Multiple (LCM) of 9 and 32 is the smallest multiple that is divisible by both 9 and 32. To find the LCM, you can use the formula LCM(a, b) = (a * b) / GCD(a, b), where GCD is the Greatest Common Divisor. In this case, the GCD of 9 and 32 is 1, so the LCM of 9 and 32 is (9 * 32) / 1 = 288.

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 13 and 65?

The least common multiple (LCM) of 13 and 65 is the smallest multiple that both numbers share. To find the LCM, you can use the formula LCM(a, b) = (|a * b|) / GCD(a, b), where GCD is the greatest common divisor. In this case, the GCD of 13 and 65 is 13, so the LCM is (|13 * 65|) / 13 = 65.


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.


What are the lest comm multiples?

The least common multiple (LCM) of two or more integers is the smallest positive integer that is divisible by all the numbers in the set. To find the LCM, one common method is to list the multiples of each number and identify the smallest common one. Alternatively, the LCM can be calculated using the formula: LCM(a, b) = (a * b) / GCD(a, b), where GCD is the greatest common divisor.
