Given numbers are 312,622,430,553

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

The LCM of 312,622,430,553 is 11536619640.

Find LCM of 312,622,430,553 with Prime Factorization

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

2 x 156 x 311 x 215 x 553 = 11536619640

Therefore, the lowest common multiple of 312,622,430,553 is 11536619640.

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.

312 x 622 x 430 x 553 = 46146478560

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.

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

622 : 1, 2, 311, 622

430 : 1, 2, 5, 10, 43, 86, 215, 430

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,622,430,553, is 1.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

622:2x 311

430:2x 5x 43

553:7x 79

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 46146478560/(1x4)

LCM = 46146478560/4

LCM = 11536619640

Thus, we can understand that the LCM of 312,622,430,553 is 11536619640.

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