Given numbers are 781,63,993

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

The LCM of 781,63,993 is 16286193.

Find LCM of 781,63,993 with Prime Factorization

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

3 x 781 x 21 x 331 = 16286193

Therefore, the lowest common multiple of 781,63,993 is 16286193.

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.

781 x 63 x 993 = 48858579

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.

781 : 1, 11, 71, 781

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

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,63,993, is 1.

Now, the common factors can be found like this.

781:11x 71

63:3x 3x 7

993:3x 331

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 = 48858579/(1x3)

LCM = 48858579/3

LCM = 16286193

Thus, we can understand that the LCM of 781,63,993 is 16286193.

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

• LCM of 474, 41, 224
• LCM of 537, 25, 949
• LCM of 446, 54, 208
