Given numbers are 160,494,220,194,660

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

The LCM of 160,494,220,194,660 is 126503520.

Find LCM of 160,494,220,194,660 with Prime Factorization

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

2 x 2 x 5 x 11 x 8 x 247 x 1 x 97 x 3 = 126503520

Therefore, the lowest common multiple of 160,494,220,194,660 is 126503520.

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.

160 x 494 x 220 x 194 x 660 = 2226461952000

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.

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

494 : 1, 2, 13, 19, 26, 38, 247, 494

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

194 : 1, 2, 97, 194

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,494,220,194,660, is 2.

Now, the common factors can be found like this.

160:2x 2x 2x 2x 2x 5

494:2x 13x 19

220:2x 2x 5x 11

194:2x 97

660:2x 2x 3x 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 5x 5x 11 = 8800

Therefore, the value for common factors is 8800.

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 = 2226461952000/(2x8800)

LCM = 2226461952000/17600

LCM = 126503520

Thus, we can understand that the LCM of 160,494,220,194,660 is 126503520.
