Given numbers are 130,720,440,953

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

The LCM of 130,720,440,953 is 98120880.

Find LCM of 130,720,440,953 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 18 x 11 x 953 = 98120880

Therefore, the lowest common multiple of 130,720,440,953 is 98120880.

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.

130 x 720 x 440 x 953 = 39248352000

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.

130 : 1, 2, 5, 10, 13, 26, 65, 130

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

953 : 1, 953

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,720,440,953, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

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

440:2x 2x 2x 5x 11

953:953

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

2x 2x 2x 2x 5x 5 = 400

Therefore, the value for common factors is 400.

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 = 39248352000/(1x400)

LCM = 39248352000/400

LCM = 98120880

Thus, we can understand that the LCM of 130,720,440,953 is 98120880.
