Given numbers are 686,869,148,979

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

The LCM of 686,869,148,979 is 3926138524.

Find LCM of 686,869,148,979 with Prime Factorization

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

2 x 11 x 343 x 79 x 74 x 89 = 3926138524

Therefore, the lowest common multiple of 686,869,148,979 is 3926138524.

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 869 x 148 x 979 = 86375047528

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

869 : 1, 11, 79, 869

148 : 1, 2, 4, 37, 74, 148

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,869,148,979, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

869:11x 79

148:2x 2x 37

979:11x 89

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 86375047528/(1x22)

LCM = 86375047528/22

LCM = 3926138524

Thus, we can understand that the LCM of 686,869,148,979 is 3926138524.
