Calculate the LCM of 817,541,143,858

Given numbers are 817,541,143,858

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

The LCM of 817,541,143,858 is 379233426.

Find LCM of 817,541,143,858 with Prime Factorization


11 817, 541, 143, 858
13 817, 541, 13, 78
817, 541, 1, 6

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

11 x 13 x 817 x 541 x 1 x 6 = 379233426

Therefore, the lowest common multiple of 817,541,143,858 is 379233426.

LCM Formula to Find Lowest Common Multiple of 817,541,143,858

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.

817 x 541 x 143 x 858 = 54230379918

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.

817 : 1, 19, 43, 817

541 : 1, 541

143 : 1, 11, 13, 143

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,541,143,858, is 1.

Now, the common factors can be found like this.

817:19x 43

541:541

143:11x 13

858:2x 3x 11x 13

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

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 54230379918/(1x143)

LCM = 54230379918/143

LCM = 379233426

Thus, we can understand that the LCM of 817,541,143,858 is 379233426.
