The LCM of 242,345,400,780,440 is 43414800.

Find LCM of 242,345,400,780,440 with Prime Factorization


2 242, 345, 400, 780, 440
2 121, 345, 200, 390, 220
2 121, 345, 100, 195, 110
3 121, 345, 50, 195, 55
5 121, 115, 50, 65, 55
11 121, 23, 10, 13, 11
1, 23, 10, 13, 11

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

2 x 2 x 2 x 3 x 5 x 11 x 1 x 23 x 10 x 13 x 11 = 43414800

Therefore, the lowest common multiple of 242,345,400,780,440 is 43414800.

LCM Formula to Find Lowest Common Multiple of 242,345,400,780,440

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.

242 x 345 x 400 x 780 x 440 = 11461507200000

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.

242 : 1, 2, 11, 22, 121, 242

345 : 1, 3, 5, 15, 23, 69, 115, 345

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,345,400,780,440, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

345:3x 5x 23

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

780:2x 2x 3x 5x 13

440:2x 2x 2x 5x 11

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 2x 3x 5x 5x 5x 11 = 264000

Therefore, the value for common factors is 264000.

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 = 11461507200000/(1x264000)

LCM = 11461507200000/264000

LCM = 43414800

Thus, we can understand that the LCM of 242,345,400,780,440 is 43414800.
