Calculate the LCM of 715,839,154,399

Given numbers are 715,839,154,399

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

The LCM of 715,839,154,399 is 478708230.

Find LCM of 715,839,154,399 with Prime Factorization


7 715, 839, 154, 399
11 715, 839, 22, 57
65, 839, 2, 57

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

7 x 11 x 65 x 839 x 2 x 57 = 478708230

Therefore, the lowest common multiple of 715,839,154,399 is 478708230.

LCM Formula to Find Lowest Common Multiple of 715,839,154,399

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.

715 x 839 x 154 x 399 = 36860533710

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

839 : 1, 839

154 : 1, 2, 7, 11, 14, 22, 77, 154

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,839,154,399, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

839:839

154:2x 7x 11

399:3x 7x 19

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

7x 11 = 77

Therefore, the value for common factors is 77.

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 = 36860533710/(1x77)

LCM = 36860533710/77

LCM = 478708230

Thus, we can understand that the LCM of 715,839,154,399 is 478708230.
