Given numbers are 817,155,279,358

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

The LCM of 817,155,279,358 is 408017970.

Find LCM of 817,155,279,358 with Prime Factorization

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

31 x 817 x 5 x 9 x 358 = 408017970

Therefore, the lowest common multiple of 817,155,279,358 is 408017970.

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.

817 x 155 x 279 x 358 = 12648557070

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.

817 : 1, 19, 43, 817

155 : 1, 5, 31, 155

279 : 1, 3, 9, 31, 93, 279

358 : 1, 2, 179, 358

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,155,279,358, is 1.

Now, the common factors can be found like this.

817:19x 43

155:5x 31

279:3x 3x 31

358:2x 179

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

31 = 31

Therefore, the value for common factors is 31.

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 = 12648557070/(1x31)

LCM = 12648557070/31

LCM = 408017970

Thus, we can understand that the LCM of 817,155,279,358 is 408017970.
