Calculate the LCM of 490,419,454,345,454

Given numbers are 490,419,454,345,454

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

The LCM of 490,419,454,345,454 is 3215770530.

Find LCM of 490,419,454,345,454 with Prime Factorization


2 490, 419, 454, 345, 454
5 245, 419, 227, 345, 227
227 49, 419, 227, 69, 227
49, 419, 1, 69, 1

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

2 x 5 x 227 x 49 x 419 x 1 x 69 x 1 = 3215770530

Therefore, the lowest common multiple of 490,419,454,345,454 is 3215770530.

LCM Formula to Find Lowest Common Multiple of 490,419,454,345,454

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.

490 x 419 x 454 x 345 x 454 = 14599598206200

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.

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

419 : 1, 419

454 : 1, 2, 227, 454

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

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,419,454,345,454, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

419:419

454:2x 227

345:3x 5x 23

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 5x 227 = 4540

Therefore, the value for common factors is 4540.

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 = 14599598206200/(1x4540)

LCM = 14599598206200/4540

LCM = 3215770530

Thus, we can understand that the LCM of 490,419,454,345,454 is 3215770530.
