Given numbers are 553,103,515,391

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

The LCM of 553,103,515,391 is 111354845.

Find LCM of 553,103,515,391 with Prime Factorization

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

103 x 553 x 1 x 5 x 391 = 111354845

Therefore, the lowest common multiple of 553,103,515,391 is 111354845.

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.

553 x 103 x 515 x 391 = 11469549035

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.

553 : 1, 7, 79, 553

103 : 1, 103

515 : 1, 5, 103, 515

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,103,515,391, is 1.

Now, the common factors can be found like this.

553:7x 79

103:103

515:5x 103

391:17x 23

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

103 = 103

Therefore, the value for common factors is 103.

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 = 11469549035/(1x103)

LCM = 11469549035/103

LCM = 111354845

Thus, we can understand that the LCM of 553,103,515,391 is 111354845.
