Given numbers are 63,61,57,68,919

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

The LCM of 63,61,57,68,919 is 4562978364.

Find LCM of 63,61,57,68,919 with Prime Factorization

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

3 x 21 x 61 x 19 x 68 x 919 = 4562978364

Therefore, the lowest common multiple of 63,61,57,68,919 is 4562978364.

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.

63 x 61 x 57 x 68 x 919 = 13688935092

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.

63 : 1, 3, 7, 9, 21, 63

61 : 1, 61

57 : 1, 3, 19, 57

68 : 1, 2, 4, 17, 34, 68

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 63,61,57,68,919, is 1.

Now, the common factors can be found like this.

63:3x 3x 7

61:61

57:3x 19

68:2x 2x 17

919:919

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

3 = 3

Therefore, the value for common factors is 3.

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 = 13688935092/(1x3)

LCM = 13688935092/3

LCM = 4562978364

Thus, we can understand that the LCM of 63,61,57,68,919 is 4562978364.

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