Given numbers are 398,763,161,581,126

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

The LCM of 398,763,161,581,126 is 5217422994.

Find LCM of 398,763,161,581,126 with Prime Factorization

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

2 x 7 x 199 x 109 x 23 x 83 x 9 = 5217422994

Therefore, the lowest common multiple of 398,763,161,581,126 is 5217422994.

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.

398 x 763 x 161 x 581 x 126 = 3579152173884

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.

398 : 1, 2, 199, 398

763 : 1, 7, 109, 763

161 : 1, 7, 23, 161

581 : 1, 7, 83, 581

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,763,161,581,126, is 1.

Now, the common factors can be found like this.

398:2x 199

763:7x 109

161:7x 23

581:7x 83

126:2x 3x 3x 7

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

2x 7x 7x 7 = 686

Therefore, the value for common factors is 686.

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 = 3579152173884/(1x686)

LCM = 3579152173884/686

LCM = 5217422994

Thus, we can understand that the LCM of 398,763,161,581,126 is 5217422994.
