Calculate the LCM of 291,855,343,817

Given numbers are 291,855,343,817

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

The LCM of 291,855,343,817 is 1223208315.

Find LCM of 291,855,343,817 with Prime Factorization


3 291, 855, 343, 817
19 97, 285, 343, 817
97, 15, 343, 43

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

3 x 19 x 97 x 15 x 343 x 43 = 1223208315

Therefore, the lowest common multiple of 291,855,343,817 is 1223208315.

LCM Formula to Find Lowest Common Multiple of 291,855,343,817

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.

291 x 855 x 343 x 817 = 69722873955

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.

291 : 1, 3, 97, 291

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

343 : 1, 7, 49, 343

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,855,343,817, is 1.

Now, the common factors can be found like this.

291:3x 97

855:3x 3x 5x 19

343:7x 7x 7

817:19x 43

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 69722873955/(1x57)

LCM = 69722873955/57

LCM = 1223208315

Thus, we can understand that the LCM of 291,855,343,817 is 1223208315.
