Given numbers are 103,979,236,206,642

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

The LCM of 103,979,236,206,642 is 7639007772.

Find LCM of 103,979,236,206,642 with Prime Factorization

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

2 x 103 x 1 x 979 x 118 x 1 x 321 = 7639007772

Therefore, the lowest common multiple of 103,979,236,206,642 is 7639007772.

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.

103 x 979 x 236 x 206 x 642 = 3147271202064

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.

103 : 1, 103

979 : 1, 11, 89, 979

236 : 1, 2, 4, 59, 118, 236

206 : 1, 2, 103, 206

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,979,236,206,642, is 1.

Now, the common factors can be found like this.

103:103

979:11x 89

236:2x 2x 59

206:2x 103

642:2x 3x 107

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

2x 2x 103 = 412

Therefore, the value for common factors is 412.

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 = 3147271202064/(1x412)

LCM = 3147271202064/412

LCM = 7639007772

Thus, we can understand that the LCM of 103,979,236,206,642 is 7639007772.
