The LCM of 400,320,150,554 is 1329600.

Find LCM of 400,320,150,554 with Prime Factorization


2 400, 320, 150, 554
2 200, 160, 75, 277
2 100, 80, 75, 277
2 50, 40, 75, 277
5 25, 20, 75, 277
5 5, 4, 15, 277
1, 4, 3, 277

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

2 x 2 x 2 x 2 x 5 x 5 x 1 x 4 x 3 x 277 = 1329600

Therefore, the lowest common multiple of 400,320,150,554 is 1329600.

LCM Formula to Find Lowest Common Multiple of 400,320,150,554

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.

400 x 320 x 150 x 554 = 10636800000

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.

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

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150

554 : 1, 2, 277, 554

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,320,150,554, is 2.

Now, the common factors can be found like this.

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

320:2x 2x 2x 2x 2x 2x 5

150:2x 3x 5x 5

554:2x 277

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 2x 5x 5x 5 = 4000

Therefore, the value for common factors is 4000.

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 = 10636800000/(2x4000)

LCM = 10636800000/8000

LCM = 1329600

Thus, we can understand that the LCM of 400,320,150,554 is 1329600.
