Given numbers are 161,970,454,454

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

The LCM of 161,970,454,454 is 35450590.

Find LCM of 161,970,454,454 with Prime Factorization

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

2 x 227 x 161 x 485 x 1 x 1 = 35450590

Therefore, the lowest common multiple of 161,970,454,454 is 35450590.

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.

161 x 970 x 454 x 454 = 32189135720

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.

161 : 1, 7, 23, 161

970 : 1, 2, 5, 10, 97, 194, 485, 970

454 : 1, 2, 227, 454

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,970,454,454, is 1.

Now, the common factors can be found like this.

161:7x 23

970:2x 5x 97

454:2x 227

454:2x 227

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 227 = 908

Therefore, the value for common factors is 908.

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 = 32189135720/(1x908)

LCM = 32189135720/908

LCM = 35450590

Thus, we can understand that the LCM of 161,970,454,454 is 35450590.
