Given numbers are 551,235,686,812

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

The LCM of 551,235,686,812 is 177653420.

Find LCM of 551,235,686,812 with Prime Factorization

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

2 x 7 x 29 x 19 x 235 x 49 x 2 = 177653420

Therefore, the lowest common multiple of 551,235,686,812 is 177653420.

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.

551 x 235 x 686 x 812 = 72127288520

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.

551 : 1, 19, 29, 551

235 : 1, 5, 47, 235

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

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,235,686,812, is 1.

Now, the common factors can be found like this.

551:19x 29

235:5x 47

686:2x 7x 7x 7

812:2x 2x 7x 29

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

2x 7x 29 = 406

Therefore, the value for common factors is 406.

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 = 72127288520/(1x406)

LCM = 72127288520/406

LCM = 177653420

Thus, we can understand that the LCM of 551,235,686,812 is 177653420.
