Calculate the LCM of 159,900,400,161

Given numbers are 159,900,400,161

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

The LCM of 159,900,400,161 is 30718800.

Find LCM of 159,900,400,161 with Prime Factorization


2 159, 900, 400, 161
2 159, 450, 200, 161
3 159, 225, 100, 161
5 53, 75, 100, 161
5 53, 15, 20, 161
53, 3, 4, 161

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

2 x 2 x 3 x 5 x 5 x 53 x 3 x 4 x 161 = 30718800

Therefore, the lowest common multiple of 159,900,400,161 is 30718800.

LCM Formula to Find Lowest Common Multiple of 159,900,400,161

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.

159 x 900 x 400 x 161 = 9215640000

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.

159 : 1, 3, 53, 159

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

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

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,900,400,161, is 1.

Now, the common factors can be found like this.

159:3x 53

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

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

161:7x 23

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 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 9215640000/(1x300)

LCM = 9215640000/300

LCM = 30718800

Thus, we can understand that the LCM of 159,900,400,161 is 30718800.
