Given numbers are 761,211,687,687

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

The LCM of 761,211,687,687 is 110312277.

Find LCM of 761,211,687,687 with Prime Factorization

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

3 x 229 x 761 x 211 x 1 x 1 = 110312277

Therefore, the lowest common multiple of 761,211,687,687 is 110312277.

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.

761 x 211 x 687 x 687 = 75784534299

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.

761 : 1, 761

211 : 1, 211

687 : 1, 3, 229, 687

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,211,687,687, is 1.

Now, the common factors can be found like this.

761:761

211:211

687:3x 229

687:3x 229

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

3x 229 = 687

Therefore, the value for common factors is 687.

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 = 75784534299/(1x687)

LCM = 75784534299/687

LCM = 110312277

Thus, we can understand that the LCM of 761,211,687,687 is 110312277.
