Given numbers are 243,161,943

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 243,161,943 is 1604043.

Find LCM of 243,161,943 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

23 x 243 x 7 x 41 = 1604043

Therefore, the lowest common multiple of 243,161,943 is 1604043.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

243 x 161 x 943 = 36892989

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

243 : 1, 3, 9, 27, 81, 243

161 : 1, 7, 23, 161

943 : 1, 23, 41, 943

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,161,943, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

161:7x 23

943:23x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

23 = 23

Therefore, the value for common factors is 23.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 36892989/(1x23)

LCM = 36892989/23

LCM = 1604043

Thus, we can understand that the LCM of 243,161,943 is 1604043.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 150, 349, 462
• LCM of 507, 311, 256
