Given numbers are 221,779,153,698,430

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

The LCM of 221,779,153,698,430 is 232523110170.

Find LCM of 221,779,153,698,430 with Prime Factorization

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

2 x 17 x 13 x 779 x 9 x 349 x 215 = 232523110170

Therefore, the lowest common multiple of 221,779,153,698,430 is 232523110170.

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.

221 x 779 x 153 x 698 x 430 = 7905785745780

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.

221 : 1, 13, 17, 221

779 : 1, 19, 41, 779

153 : 1, 3, 9, 17, 51, 153

698 : 1, 2, 349, 698

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 221,779,153,698,430, is 1.

Now, the common factors can be found like this.

221:13x 17

779:19x 41

153:3x 3x 17

698:2x 349

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 17 = 34

Therefore, the value for common factors is 34.

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 = 7905785745780/(1x34)

LCM = 7905785745780/34

LCM = 232523110170

Thus, we can understand that the LCM of 221,779,153,698,430 is 232523110170.
