Given numbers are 421,489,815,892

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

The LCM of 421,489,815,892 is 918175740.

Find LCM of 421,489,815,892 with Prime Factorization

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

163 x 421 x 3 x 5 x 892 = 918175740

Therefore, the lowest common multiple of 421,489,815,892 is 918175740.

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.

421 x 489 x 815 x 892 = 149662645620

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.

421 : 1, 421

489 : 1, 3, 163, 489

815 : 1, 5, 163, 815

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 421,489,815,892, is 1.

Now, the common factors can be found like this.

421:421

489:3x 163

815:5x 163

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.

163 = 163

Therefore, the value for common factors is 163.

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 = 149662645620/(1x163)

LCM = 149662645620/163

LCM = 918175740

Thus, we can understand that the LCM of 421,489,815,892 is 918175740.
