Given numbers are 278,531,556,821

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

The LCM of 278,531,556,821 is 242388756.

Find LCM of 278,531,556,821 with Prime Factorization

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

2 x 139 x 1 x 531 x 2 x 821 = 242388756

Therefore, the lowest common multiple of 278,531,556,821 is 242388756.

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.

278 x 531 x 556 x 821 = 67384074168

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.

278 : 1, 2, 139, 278

531 : 1, 3, 9, 59, 177, 531

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

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,531,556,821, is 1.

Now, the common factors can be found like this.

278:2x 139

531:3x 3x 59

556:2x 2x 139

821:821

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

2x 139 = 278

Therefore, the value for common factors is 278.

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 = 67384074168/(1x278)

LCM = 67384074168/278

LCM = 242388756

Thus, we can understand that the LCM of 278,531,556,821 is 242388756.
