Given numbers are 218,290,335,391

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

The LCM of 218,290,335,391 is 828087170.

Find LCM of 218,290,335,391 with Prime Factorization

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

2 x 5 x 109 x 29 x 67 x 391 = 828087170

Therefore, the lowest common multiple of 218,290,335,391 is 828087170.

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.

218 x 290 x 335 x 391 = 8280871700

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.

218 : 1, 2, 109, 218

290 : 1, 2, 5, 10, 29, 58, 145, 290

335 : 1, 5, 67, 335

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,290,335,391, is 1.

Now, the common factors can be found like this.

218:2x 109

290:2x 5x 29

335:5x 67

391:17x 23

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 8280871700/(1x10)

LCM = 8280871700/10

LCM = 828087170

Thus, we can understand that the LCM of 218,290,335,391 is 828087170.
