Calculate the LCM of 369,450,434,320

Given numbers are 369,450,434,320

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

The LCM of 369,450,434,320 is 128116800.

Find LCM of 369,450,434,320 with Prime Factorization


2 369, 450, 434, 320
3 369, 225, 217, 160
3 123, 75, 217, 160
5 41, 25, 217, 160
41, 5, 217, 32

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

2 x 3 x 3 x 5 x 41 x 5 x 217 x 32 = 128116800

Therefore, the lowest common multiple of 369,450,434,320 is 128116800.

LCM Formula to Find Lowest Common Multiple of 369,450,434,320

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.

369 x 450 x 434 x 320 = 23061024000

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.

369 : 1, 3, 9, 41, 123, 369

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

434 : 1, 2, 7, 14, 31, 62, 217, 434

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,450,434,320, is 1.

Now, the common factors can be found like this.

369:3x 3x 41

450:2x 3x 3x 5x 5

434:2x 7x 31

320:2x 2x 2x 2x 2x 2x 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 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 = 23061024000/(1x180)

LCM = 23061024000/180

LCM = 128116800

Thus, we can understand that the LCM of 369,450,434,320 is 128116800.
