Given numbers are 154,415,389,763

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

The LCM of 154,415,389,763 is 2709847910.

Find LCM of 154,415,389,763 with Prime Factorization

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

7 x 22 x 415 x 389 x 109 = 2709847910

Therefore, the lowest common multiple of 154,415,389,763 is 2709847910.

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.

154 x 415 x 389 x 763 = 18968935370

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.

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

415 : 1, 5, 83, 415

389 : 1, 389

763 : 1, 7, 109, 763

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,415,389,763, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

415:5x 83

389:389

763:7x 109

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

7 = 7

Therefore, the value for common factors is 7.

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 = 18968935370/(1x7)

LCM = 18968935370/7

LCM = 2709847910

Thus, we can understand that the LCM of 154,415,389,763 is 2709847910.
