Given numbers are 220,138,445,386

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

The LCM of 220,138,445,386 is 260746860.

Find LCM of 220,138,445,386 with Prime Factorization

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

2 x 5 x 22 x 69 x 89 x 193 = 260746860

Therefore, the lowest common multiple of 220,138,445,386 is 260746860.

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.

220 x 138 x 445 x 386 = 5214937200

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.

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

138 : 1, 2, 3, 6, 23, 46, 69, 138

445 : 1, 5, 89, 445

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,138,445,386, is 1.

Now, the common factors can be found like this.

220:2x 2x 5x 11

138:2x 3x 23

445:5x 89

386:2x 193

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 5 = 20

Therefore, the value for common factors is 20.

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 = 5214937200/(1x20)

LCM = 5214937200/20

LCM = 260746860

Thus, we can understand that the LCM of 220,138,445,386 is 260746860.
