Given numbers are 783,213,991

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

The LCM of 783,213,991 is 55092663.

Find LCM of 783,213,991 with Prime Factorization

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

3 x 261 x 71 x 991 = 55092663

Therefore, the lowest common multiple of 783,213,991 is 55092663.

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.

783 x 213 x 991 = 165277989

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.

783 : 1, 3, 9, 27, 29, 87, 261, 783

213 : 1, 3, 71, 213

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,213,991, is 1.

Now, the common factors can be found like this.

783:3x 3x 3x 29

213:3x 71

991:991

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 = 165277989/(1x3)

LCM = 165277989/3

LCM = 55092663

Thus, we can understand that the LCM of 783,213,991 is 55092663.

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

• LCM of 501, 273, 950
• LCM of 697, 743, 964
