Given numbers are 380,221,437,943

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

The LCM of 380,221,437,943 is 79193140.

Find LCM of 380,221,437,943 with Prime Factorization

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

19 x 23 x 20 x 221 x 1 x 41 = 79193140

Therefore, the lowest common multiple of 380,221,437,943 is 79193140.

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.

380 x 221 x 437 x 943 = 34607402180

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.

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

221 : 1, 13, 17, 221

437 : 1, 19, 23, 437

943 : 1, 23, 41, 943

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,221,437,943, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

221:13x 17

437:19x 23

943:23x 41

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

19x 23 = 437

Therefore, the value for common factors is 437.

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 = 34607402180/(1x437)

LCM = 34607402180/437

LCM = 79193140

Thus, we can understand that the LCM of 380,221,437,943 is 79193140.
