Given numbers are 842,770,214,643

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

The LCM of 842,770,214,643 is 22303220170.

Find LCM of 842,770,214,643 with Prime Factorization

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

2 x 421 x 385 x 107 x 643 = 22303220170

Therefore, the lowest common multiple of 842,770,214,643 is 22303220170.

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.

842 x 770 x 214 x 643 = 89212880680

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.

842 : 1, 2, 421, 842

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

214 : 1, 2, 107, 214

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,770,214,643, is 1.

Now, the common factors can be found like this.

842:2x 421

770:2x 5x 7x 11

214:2x 107

643:643

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 = 89212880680/(1x4)

LCM = 89212880680/4

LCM = 22303220170

Thus, we can understand that the LCM of 842,770,214,643 is 22303220170.
