Given numbers are 686,201,551,551

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

The LCM of 686,201,551,551 is 75975186.

Find LCM of 686,201,551,551 with Prime Factorization

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

19 x 29 x 686 x 201 x 1 x 1 = 75975186

Therefore, the lowest common multiple of 686,201,551,551 is 75975186.

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.

686 x 201 x 551 x 551 = 41862327486

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

201 : 1, 3, 67, 201

551 : 1, 19, 29, 551

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,201,551,551, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

201:3x 67

551:19x 29

551:19x 29

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

19x 29 = 551

Therefore, the value for common factors is 551.

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 = 41862327486/(1x551)

LCM = 41862327486/551

LCM = 75975186

Thus, we can understand that the LCM of 686,201,551,551 is 75975186.

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