Calculate the LCM of 989,715,515,800

Given numbers are 989,715,515,800

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

The LCM of 989,715,515,800 is 11653584800.

Find LCM of 989,715,515,800 with Prime Factorization


5 989, 715, 515, 800
989, 143, 103, 160

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

5 x 989 x 143 x 103 x 160 = 11653584800

Therefore, the lowest common multiple of 989,715,515,800 is 11653584800.

LCM Formula to Find Lowest Common Multiple of 989,715,515,800

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.

989 x 715 x 515 x 800 = 291339620000

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.

989 : 1, 23, 43, 989

715 : 1, 5, 11, 13, 55, 65, 143, 715

515 : 1, 5, 103, 515

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,715,515,800, is 1.

Now, the common factors can be found like this.

989:23x 43

715:5x 11x 13

515:5x 103

800:2x 2x 2x 2x 2x 5x 5

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 291339620000/(1x25)

LCM = 291339620000/25

LCM = 11653584800

Thus, we can understand that the LCM of 989,715,515,800 is 11653584800.
