Calculate the LCM of 900,128,915,723

Given numbers are 900,128,915,723

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

The LCM of 900,128,915,723 is 423388800.

Find LCM of 900,128,915,723 with Prime Factorization


2 900, 128, 915, 723
2 450, 64, 915, 723
3 225, 32, 915, 723
5 75, 32, 305, 241
15, 32, 61, 241

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

2 x 2 x 3 x 5 x 15 x 32 x 61 x 241 = 423388800

Therefore, the lowest common multiple of 900,128,915,723 is 423388800.

LCM Formula to Find Lowest Common Multiple of 900,128,915,723

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.

900 x 128 x 915 x 723 = 76209984000

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.

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

128 : 1, 2, 4, 8, 16, 32, 64, 128

915 : 1, 3, 5, 15, 61, 183, 305, 915

723 : 1, 3, 241, 723

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,128,915,723, is 1.

Now, the common factors can be found like this.

900:2x 2x 3x 3x 5x 5

128:2x 2x 2x 2x 2x 2x 2

915:3x 5x 61

723:3x 241

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 76209984000/(1x180)

LCM = 76209984000/180

LCM = 423388800

Thus, we can understand that the LCM of 900,128,915,723 is 423388800.
