Given numbers are 557,580,162,428

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

The LCM of 557,580,162,428 is 2799961020.

Find LCM of 557,580,162,428 with Prime Factorization

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

2 x 2 x 557 x 145 x 81 x 107 = 2799961020

Therefore, the lowest common multiple of 557,580,162,428 is 2799961020.

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 580 x 162 x 428 = 22399688160

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,580,162,428, is 1.

Now, the common factors can be found like this.

557:557

580:2x 2x 5x 29

162:2x 3x 3x 3x 3

428:2x 2x 107

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 22399688160/(1x8)

LCM = 22399688160/8

LCM = 2799961020

Thus, we can understand that the LCM of 557,580,162,428 is 2799961020.
