Calculate the LCM of 993,758,638,867

Given numbers are 993,758,638,867

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

The LCM of 993,758,638,867 is 69391612554.

Find LCM of 993,758,638,867 with Prime Factorization


2 993, 758, 638, 867
3 993, 379, 319, 867
331, 379, 319, 289

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

2 x 3 x 331 x 379 x 319 x 289 = 69391612554

Therefore, the lowest common multiple of 993,758,638,867 is 69391612554.

LCM Formula to Find Lowest Common Multiple of 993,758,638,867

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.

993 x 758 x 638 x 867 = 416349675324

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.

993 : 1, 3, 331, 993

758 : 1, 2, 379, 758

638 : 1, 2, 11, 22, 29, 58, 319, 638

867 : 1, 3, 17, 51, 289, 867

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,758,638,867, is 1.

Now, the common factors can be found like this.

993:3x 331

758:2x 379

638:2x 11x 29

867:3x 17x 17

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 416349675324/(1x6)

LCM = 416349675324/6

LCM = 69391612554

Thus, we can understand that the LCM of 993,758,638,867 is 69391612554.
