Calculate the LCM of 782,447,138,207

Given numbers are 782,447,138,207

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

The LCM of 782,447,138,207 is 1048662.

Find LCM of 782,447,138,207 with Prime Factorization


2 782, 447, 138, 207
3 391, 447, 69, 207
23 391, 149, 23, 69
17, 149, 1, 3

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

2 x 3 x 23 x 17 x 149 x 1 x 3 = 1048662

Therefore, the lowest common multiple of 782,447,138,207 is 1048662.

LCM Formula to Find Lowest Common Multiple of 782,447,138,207

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.

782 x 447 x 138 x 207 = 9985359564

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

447 : 1, 3, 149, 447

138 : 1, 2, 3, 6, 23, 46, 69, 138

207 : 1, 3, 9, 23, 69, 207

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,447,138,207, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

447:3x 149

138:2x 3x 23

207:3x 3x 23

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

2x 3x 3x 23x 23 = 9522

Therefore, the value for common factors is 9522.

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 = 9985359564/(1x9522)

LCM = 9985359564/9522

LCM = 1048662

Thus, we can understand that the LCM of 782,447,138,207 is 1048662.
