Given numbers are 420,481,329,957

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

The LCM of 420,481,329,957 is 3028885860.

Find LCM of 420,481,329,957 with Prime Factorization

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

3 x 7 x 20 x 481 x 47 x 319 = 3028885860

Therefore, the lowest common multiple of 420,481,329,957 is 3028885860.

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.

420 x 481 x 329 x 957 = 63606603060

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

481 : 1, 13, 37, 481

329 : 1, 7, 47, 329

957 : 1, 3, 11, 29, 33, 87, 319, 957

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,481,329,957, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

481:13x 37

329:7x 47

957:3x 11x 29

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 63606603060/(1x21)

LCM = 63606603060/21

LCM = 3028885860

Thus, we can understand that the LCM of 420,481,329,957 is 3028885860.
