Find LCM of 800,440,957,161 with Prime Factorization


2 800, 440, 957, 161
2 400, 220, 957, 161
2 200, 110, 957, 161
5 100, 55, 957, 161
11 20, 11, 957, 161
20, 1, 87, 161

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

2 x 2 x 2 x 5 x 11 x 20 x 1 x 87 x 161 = 123261600

Therefore, the lowest common multiple of 800,440,957,161 is 123261600.

LCM Formula to Find Lowest Common Multiple of 800,440,957,161

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.

800 x 440 x 957 x 161 = 54235104000

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.

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

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

957 : 1, 3, 11, 29, 33, 87, 319, 957

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,440,957,161, is 1.

Now, the common factors can be found like this.

800:2x 2x 2x 2x 2x 5x 5

440:2x 2x 2x 5x 11

957:3x 11x 29

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 2x 5x 11 = 440

Therefore, the value for common factors is 440.

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 = 54235104000/(1x440)

LCM = 54235104000/440

LCM = 123261600

Thus, we can understand that the LCM of 800,440,957,161 is 123261600.
