Given numbers are 313,390,987

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

The LCM of 313,390,987 is 40161030.

Find LCM of 313,390,987 with Prime Factorization

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

3 x 313 x 130 x 329 = 40161030

Therefore, the lowest common multiple of 313,390,987 is 40161030.

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.

313 x 390 x 987 = 120483090

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.

313 : 1, 313

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 313,390,987, is 1.

Now, the common factors can be found like this.

313:313

390:2x 3x 5x 13

987:3x 7x 47

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

3 = 3

Therefore, the value for common factors is 3.

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 = 120483090/(1x3)

LCM = 120483090/3

LCM = 40161030

Thus, we can understand that the LCM of 313,390,987 is 40161030.
