Given numbers are 490,409,781,671

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

The LCM of 490,409,781,671 is 9547732810.

Find LCM of 490,409,781,671 with Prime Factorization

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

11 x 490 x 409 x 71 x 61 = 9547732810

Therefore, the lowest common multiple of 490,409,781,671 is 9547732810.

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 409 x 781 x 671 = 105025060910

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

409 : 1, 409

781 : 1, 11, 71, 781

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,409,781,671, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

409:409

781:11x 71

671:11x 61

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

11 = 11

Therefore, the value for common factors is 11.

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 = 105025060910/(1x11)

LCM = 105025060910/11

LCM = 9547732810

Thus, we can understand that the LCM of 490,409,781,671 is 9547732810.
