Given numbers are 421,517,380,513

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

The LCM of 421,517,380,513 is 2233160820.

Find LCM of 421,517,380,513 with Prime Factorization

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

19 x 421 x 517 x 20 x 27 = 2233160820

Therefore, the lowest common multiple of 421,517,380,513 is 2233160820.

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.

421 x 517 x 380 x 513 = 42430055580

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.

421 : 1, 421

517 : 1, 11, 47, 517

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

513 : 1, 3, 9, 19, 27, 57, 171, 513

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,517,380,513, is 1.

Now, the common factors can be found like this.

421:421

517:11x 47

380:2x 2x 5x 19

513:3x 3x 3x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 42430055580/(1x19)

LCM = 42430055580/19

LCM = 2233160820

Thus, we can understand that the LCM of 421,517,380,513 is 2233160820.
