Given numbers are 442,221,195,743

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

The LCM of 442,221,195,743 is 4926090.

Find LCM of 442,221,195,743 with Prime Factorization

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

13 x 17 x 2 x 1 x 15 x 743 = 4926090

Therefore, the lowest common multiple of 442,221,195,743 is 4926090.

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.

442 x 221 x 195 x 743 = 14152656570

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

221 : 1, 13, 17, 221

195 : 1, 3, 5, 13, 15, 39, 65, 195

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,221,195,743, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

221:13x 17

195:3x 5x 13

743:743

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

13x 13x 17 = 2873

Therefore, the value for common factors is 2873.

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 = 14152656570/(1x2873)

LCM = 14152656570/2873

LCM = 4926090

Thus, we can understand that the LCM of 442,221,195,743 is 4926090.
