Given numbers are 650,128,235,345,490

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

The LCM of 650,128,235,345,490 is 6610531200.

Find LCM of 650,128,235,345,490 with Prime Factorization

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

2 x 5 x 65 x 64 x 47 x 69 x 49 = 6610531200

Therefore, the lowest common multiple of 650,128,235,345,490 is 6610531200.

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.

650 x 128 x 235 x 345 x 490 = 3305265600000

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.

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

128 : 1, 2, 4, 8, 16, 32, 64, 128

235 : 1, 5, 47, 235

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

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,128,235,345,490, is 1.

Now, the common factors can be found like this.

650:2x 5x 5x 13

128:2x 2x 2x 2x 2x 2x 2

235:5x 47

345:3x 5x 23

490:2x 5x 7x 7

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 5x 5x 5 = 500

Therefore, the value for common factors is 500.

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 = 3305265600000/(1x500)

LCM = 3305265600000/500

LCM = 6610531200

Thus, we can understand that the LCM of 650,128,235,345,490 is 6610531200.
