Given numbers are 490,662,428,421,454

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

The LCM of 490,662,428,421,454 is 3317002510220.

Find LCM of 490,662,428,421,454 with Prime Factorization

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

2 x 245 x 331 x 214 x 421 x 227 = 3317002510220

Therefore, the lowest common multiple of 490,662,428,421,454 is 3317002510220.

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 662 x 428 x 421 x 454 = 26536020081760

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

662 : 1, 2, 331, 662

428 : 1, 2, 4, 107, 214, 428

421 : 1, 421

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,662,428,421,454, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

662:2x 331

428:2x 2x 107

421:421

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 2 = 8

Therefore, the value for common factors is 8.

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 = 26536020081760/(1x8)

LCM = 26536020081760/8

LCM = 3317002510220

Thus, we can understand that the LCM of 490,662,428,421,454 is 3317002510220.
