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

The LCM of 187,459,720 is 403920.

Find LCM of 187,459,720 with Prime Factorization


3 187, 459, 720
3 187, 153, 240
17 187, 51, 80
11, 3, 80

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

3 x 3 x 17 x 11 x 3 x 80 = 403920

Therefore, the lowest common multiple of 187,459,720 is 403920.

LCM Formula to Find Lowest Common Multiple of 187,459,720

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.

187 x 459 x 720 = 61799760

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.

187 : 1, 11, 17, 187

459 : 1, 3, 9, 17, 27, 51, 153, 459

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,459,720, is 1.

Now, the common factors can be found like this.

187:11x 17

459:3x 3x 3x 17

720:2x 2x 2x 2x 3x 3x 5

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

3x 3x 17 = 153

Therefore, the value for common factors is 153.

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 = 61799760/(1x153)

LCM = 61799760/153

LCM = 403920

Thus, we can understand that the LCM of 187,459,720 is 403920.
