Given numbers are 361,420,551

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

The LCM of 361,420,551 is 4396980.

Find LCM of 361,420,551 with Prime Factorization

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

19 x 19 x 420 x 29 = 4396980

Therefore, the lowest common multiple of 361,420,551 is 4396980.

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.

361 x 420 x 551 = 83542620

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.

361 : 1, 19, 361

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

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,420,551, is 1.

Now, the common factors can be found like this.

361:19x 19

420:2x 2x 3x 5x 7

551:19x 29

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 = 83542620/(1x19)

LCM = 83542620/19

LCM = 4396980

Thus, we can understand that the LCM of 361,420,551 is 4396980.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 853, 835, 835
