Find LCM of 845,180,531,400 with Prime Factorization


2 845, 180, 531, 400
2 845, 90, 531, 200
3 845, 45, 531, 100
3 845, 15, 177, 100
5 845, 5, 59, 100
169, 1, 59, 20

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

2 x 2 x 3 x 3 x 5 x 169 x 1 x 59 x 20 = 35895600

Therefore, the lowest common multiple of 845,180,531,400 is 35895600.

LCM Formula to Find Lowest Common Multiple of 845,180,531,400

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.

845 x 180 x 531 x 400 = 32306040000

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.

845 : 1, 5, 13, 65, 169, 845

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

531 : 1, 3, 9, 59, 177, 531

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,180,531,400, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

180:2x 2x 3x 3x 5

531:3x 3x 59

400:2x 2x 2x 2x 5x 5

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 5x 5 = 900

Therefore, the value for common factors is 900.

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 = 32306040000/(1x900)

LCM = 32306040000/900

LCM = 35895600

Thus, we can understand that the LCM of 845,180,531,400 is 35895600.
