Calculate the LCM of 668,143,899,455

Given numbers are 668,143,899,455

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

The LCM of 668,143,899,455 is 3005662660.

Find LCM of 668,143,899,455 with Prime Factorization


13 668, 143, 899, 455
668, 11, 899, 35

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

13 x 668 x 11 x 899 x 35 = 3005662660

Therefore, the lowest common multiple of 668,143,899,455 is 3005662660.

LCM Formula to Find Lowest Common Multiple of 668,143,899,455

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.

668 x 143 x 899 x 455 = 39073614580

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.

668 : 1, 2, 4, 167, 334, 668

143 : 1, 11, 13, 143

899 : 1, 29, 31, 899

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,143,899,455, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

143:11x 13

899:29x 31

455:5x 7x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 39073614580/(1x13)

LCM = 39073614580/13

LCM = 3005662660

Thus, we can understand that the LCM of 668,143,899,455 is 3005662660.
