Given numbers are 131,223,669,787

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

The LCM of 131,223,669,787 is 68971893.

Find LCM of 131,223,669,787 with Prime Factorization

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

223 x 131 x 1 x 3 x 787 = 68971893

Therefore, the lowest common multiple of 131,223,669,787 is 68971893.

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.

131 x 223 x 669 x 787 = 15380732139

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.

131 : 1, 131

223 : 1, 223

669 : 1, 3, 223, 669

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,223,669,787, is 1.

Now, the common factors can be found like this.

131:131

223:223

669:3x 223

787:787

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

223 = 223

Therefore, the value for common factors is 223.

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 = 15380732139/(1x223)

LCM = 15380732139/223

LCM = 68971893

Thus, we can understand that the LCM of 131,223,669,787 is 68971893.

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