Given numbers are 2,989,645,129

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

The LCM of 2,989,645,129 is 29670.

Find LCM of 2,989,645,129 with Prime Factorization

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

3 x 43 x 2 x 23 x 5 x 1 = 29670

Therefore, the lowest common multiple of 2,989,645,129 is 29670.

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.

2 x 989 x 645 x 129 = 164579490

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.

2 : 1, 2

989 : 1, 23, 43, 989

645 : 1, 3, 5, 15, 43, 129, 215, 645

129 : 1, 3, 43, 129

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,989,645,129, is 1.

Now, the common factors can be found like this.

2:2

989:23x 43

645:3x 5x 43

129:3x 43

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

3x 43x 43 = 5547

Therefore, the value for common factors is 5547.

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 = 164579490/(1x5547)

LCM = 164579490/5547

LCM = 29670

Thus, we can understand that the LCM of 2,989,645,129 is 29670.
