Given numbers are 163,290,640,760,490

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

The LCM of 163,290,640,760,490 is 2816535680.

Find LCM of 163,290,640,760,490 with Prime Factorization

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

2 x 2 x 2 x 5 x 163 x 29 x 16 x 19 x 49 = 2816535680

Therefore, the lowest common multiple of 163,290,640,760,490 is 2816535680.

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.

163 x 290 x 640 x 760 x 490 = 11266142720000

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.

163 : 1, 163

290 : 1, 2, 5, 10, 29, 58, 145, 290

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

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 163,290,640,760,490, is 1.

Now, the common factors can be found like this.

163:163

290:2x 5x 29

640:2x 2x 2x 2x 2x 2x 2x 5

760:2x 2x 2x 5x 19

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 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 = 11266142720000/(1x4000)

LCM = 11266142720000/4000

LCM = 2816535680

Thus, we can understand that the LCM of 163,290,640,760,490 is 2816535680.
