Given numbers are 643,445,430,892

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

The LCM of 643,445,430,892 is 10974994060.

Find LCM of 643,445,430,892 with Prime Factorization

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

2 x 5 x 643 x 89 x 43 x 446 = 10974994060

Therefore, the lowest common multiple of 643,445,430,892 is 10974994060.

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.

643 x 445 x 430 x 892 = 109749940600

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.

643 : 1, 643

445 : 1, 5, 89, 445

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

892 : 1, 2, 4, 223, 446, 892

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,445,430,892, is 1.

Now, the common factors can be found like this.

643:643

445:5x 89

430:2x 5x 43

892:2x 2x 223

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 109749940600/(1x10)

LCM = 109749940600/10

LCM = 10974994060

Thus, we can understand that the LCM of 643,445,430,892 is 10974994060.
