Given numbers are 279,217,943,445

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

The LCM of 279,217,943,445 is 819547155.

Find LCM of 279,217,943,445 with Prime Factorization

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

31 x 9 x 7 x 943 x 445 = 819547155

Therefore, the lowest common multiple of 279,217,943,445 is 819547155.

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.

279 x 217 x 943 x 445 = 25405961805

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.

279 : 1, 3, 9, 31, 93, 279

217 : 1, 7, 31, 217

943 : 1, 23, 41, 943

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,217,943,445, is 1.

Now, the common factors can be found like this.

279:3x 3x 31

217:7x 31

943:23x 41

445:5x 89

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

31 = 31

Therefore, the value for common factors is 31.

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 = 25405961805/(1x31)

LCM = 25405961805/31

LCM = 819547155

Thus, we can understand that the LCM of 279,217,943,445 is 819547155.
