Given numbers are 217,556,470,492

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

The LCM of 217,556,470,492 is 3487446060.

Find LCM of 217,556,470,492 with Prime Factorization

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

2 x 2 x 217 x 139 x 235 x 123 = 3487446060

Therefore, the lowest common multiple of 217,556,470,492 is 3487446060.

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.

217 x 556 x 470 x 492 = 27899568480

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.

217 : 1, 7, 31, 217

556 : 1, 2, 4, 139, 278, 556

470 : 1, 2, 5, 10, 47, 94, 235, 470

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,556,470,492, is 1.

Now, the common factors can be found like this.

217:7x 31

556:2x 2x 139

470:2x 5x 47

492:2x 2x 3x 41

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 27899568480/(1x8)

LCM = 27899568480/8

LCM = 3487446060

Thus, we can understand that the LCM of 217,556,470,492 is 3487446060.
