Given numbers are 129,423,987,619

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

The LCM of 129,423,987,619 is 78812937.

Find LCM of 129,423,987,619 with Prime Factorization

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

3 x 47 x 43 x 3 x 7 x 619 = 78812937

Therefore, the lowest common multiple of 129,423,987,619 is 78812937.

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.

129 x 423 x 987 x 619 = 33337872351

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.

129 : 1, 3, 43, 129

423 : 1, 3, 9, 47, 141, 423

987 : 1, 3, 7, 21, 47, 141, 329, 987

619 : 1, 619

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,423,987,619, is 1.

Now, the common factors can be found like this.

129:3x 43

423:3x 3x 47

987:3x 7x 47

619:619

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

3x 3x 47 = 423

Therefore, the value for common factors is 423.

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 = 33337872351/(1x423)

LCM = 33337872351/423

LCM = 78812937

Thus, we can understand that the LCM of 129,423,987,619 is 78812937.
