Given numbers are 557,471,642

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

The LCM of 557,471,642 is 56142258.

Find LCM of 557,471,642 with Prime Factorization

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

3 x 557 x 157 x 214 = 56142258

Therefore, the lowest common multiple of 557,471,642 is 56142258.

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 471 x 642 = 168426774

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

471 : 1, 3, 157, 471

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,471,642, is 1.

Now, the common factors can be found like this.

557:557

471:3x 157

642:2x 3x 107

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

3 = 3

Therefore, the value for common factors is 3.

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 = 168426774/(1x3)

LCM = 168426774/3

LCM = 56142258

Thus, we can understand that the LCM of 557,471,642 is 56142258.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 843, 618, 769
• LCM of 412, 165, 697
