Calculate the LCM of 817,763,815,684

Given numbers are 817,763,815,684

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

The LCM of 817,763,815,684 is 18289705140.

Find LCM of 817,763,815,684 with Prime Factorization


19 817, 763, 815, 684
43, 763, 815, 36

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

19 x 43 x 763 x 815 x 36 = 18289705140

Therefore, the lowest common multiple of 817,763,815,684 is 18289705140.

LCM Formula to Find Lowest Common Multiple of 817,763,815,684

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 763 x 815 x 684 = 347504397660

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

763 : 1, 7, 109, 763

815 : 1, 5, 163, 815

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,763,815,684, is 1.

Now, the common factors can be found like this.

817:19x 43

763:7x 109

815:5x 163

684:2x 2x 3x 3x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 347504397660/(1x19)

LCM = 347504397660/19

LCM = 18289705140

Thus, we can understand that the LCM of 817,763,815,684 is 18289705140.
