Given numbers are 557,207,437,821

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

The LCM of 557,207,437,821 is 1798549101.

Find LCM of 557,207,437,821 with Prime Factorization

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

23 x 557 x 9 x 19 x 821 = 1798549101

Therefore, the lowest common multiple of 557,207,437,821 is 1798549101.

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.

557 x 207 x 437 x 821 = 41366629323

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.

557 : 1, 557

207 : 1, 3, 9, 23, 69, 207

437 : 1, 19, 23, 437

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,207,437,821, is 1.

Now, the common factors can be found like this.

557:557

207:3x 3x 23

437:19x 23

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.

23 = 23

Therefore, the value for common factors is 23.

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 = 41366629323/(1x23)

LCM = 41366629323/23

LCM = 1798549101

Thus, we can understand that the LCM of 557,207,437,821 is 1798549101.
