Calculate the LCM of 581,490,835,668

Given numbers are 581,490,835,668

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

The LCM of 581,490,835,668 is 13583780.

Find LCM of 581,490,835,668 with Prime Factorization


2 581, 490, 835, 668
5 581, 245, 835, 334
7 581, 49, 167, 334
167 83, 7, 167, 334
83, 7, 1, 2

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

2 x 5 x 7 x 167 x 83 x 7 x 1 x 2 = 13583780

Therefore, the lowest common multiple of 581,490,835,668 is 13583780.

LCM Formula to Find Lowest Common Multiple of 581,490,835,668

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.

581 x 490 x 835 x 668 = 158794388200

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.

581 : 1, 7, 83, 581

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

835 : 1, 5, 167, 835

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,490,835,668, is 1.

Now, the common factors can be found like this.

581:7x 83

490:2x 5x 7x 7

835:5x 167

668:2x 2x 167

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

2x 5x 7x 167 = 11690

Therefore, the value for common factors is 11690.

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 = 158794388200/(1x11690)

LCM = 158794388200/11690

LCM = 13583780

Thus, we can understand that the LCM of 581,490,835,668 is 13583780.
