Given numbers are 691,724,872,987

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

The LCM of 691,724,872,987 is 107644107144.

Find LCM of 691,724,872,987 with Prime Factorization

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

2 x 2 x 691 x 181 x 218 x 987 = 107644107144

Therefore, the lowest common multiple of 691,724,872,987 is 107644107144.

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.

691 x 724 x 872 x 987 = 430576428576

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.

691 : 1, 691

724 : 1, 2, 4, 181, 362, 724

872 : 1, 2, 4, 8, 109, 218, 436, 872

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,724,872,987, is 1.

Now, the common factors can be found like this.

691:691

724:2x 2x 181

872:2x 2x 2x 109

987:3x 7x 47

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 = 430576428576/(1x4)

LCM = 430576428576/4

LCM = 107644107144

Thus, we can understand that the LCM of 691,724,872,987 is 107644107144.
