Given numbers are 643,471,209,158,158

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

The LCM of 643,471,209,158,158 is 10000811766.

Find LCM of 643,471,209,158,158 with Prime Factorization

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

2 x 79 x 643 x 471 x 209 x 1 x 1 = 10000811766

Therefore, the lowest common multiple of 643,471,209,158,158 is 10000811766.

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 471 x 209 x 158 x 158 = 1580128259028

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

471 : 1, 3, 157, 471

209 : 1, 11, 19, 209

158 : 1, 2, 79, 158

158 : 1, 2, 79, 158

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,471,209,158,158, is 1.

Now, the common factors can be found like this.

643:643

471:3x 157

209:11x 19

158:2x 79

158:2x 79

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

2x 79 = 158

Therefore, the value for common factors is 158.

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 = 1580128259028/(1x158)

LCM = 1580128259028/158

LCM = 10000811766

Thus, we can understand that the LCM of 643,471,209,158,158 is 10000811766.
