Calculate the LCM of 817,819,265,742

Given numbers are 817,819,265,742

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

The LCM of 817,819,265,742 is 354635190.

Find LCM of 817,819,265,742 with Prime Factorization


7 817, 819, 265, 742
53 817, 117, 265, 106
817, 117, 5, 2

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

7 x 53 x 817 x 117 x 5 x 2 = 354635190

Therefore, the lowest common multiple of 817,819,265,742 is 354635190.

LCM Formula to Find Lowest Common Multiple of 817,819,265,742

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 819 x 265 x 742 = 131569655490

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

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

265 : 1, 5, 53, 265

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,819,265,742, is 1.

Now, the common factors can be found like this.

817:19x 43

819:3x 3x 7x 13

265:5x 53

742:2x 7x 53

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

7x 53 = 371

Therefore, the value for common factors is 371.

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 = 131569655490/(1x371)

LCM = 131569655490/371

LCM = 354635190

Thus, we can understand that the LCM of 817,819,265,742 is 354635190.
