Given numbers are 612,138,578,493,430

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

The LCM of 612,138,578,493,430 is 1491985620.

Find LCM of 612,138,578,493,430 with Prime Factorization

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

2 x 3 x 17 x 6 x 23 x 17 x 29 x 215 = 1491985620

Therefore, the lowest common multiple of 612,138,578,493,430 is 1491985620.

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.

612 x 138 x 578 x 493 x 430 = 10348412260320

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.

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

138 : 1, 2, 3, 6, 23, 46, 69, 138

578 : 1, 2, 17, 34, 289, 578

493 : 1, 17, 29, 493

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,138,578,493,430, is 1.

Now, the common factors can be found like this.

612:2x 2x 3x 3x 17

138:2x 3x 23

578:2x 17x 17

493:17x 29

430:2x 5x 43

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 2x 3x 17x 17 = 6936

Therefore, the value for common factors is 6936.

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 = 10348412260320/(1x6936)

LCM = 10348412260320/6936

LCM = 1491985620

Thus, we can understand that the LCM of 612,138,578,493,430 is 1491985620.
