Given numbers are 218,403,268,639

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

The LCM of 218,403,268,639 is 7522586604.

Find LCM of 218,403,268,639 with Prime Factorization

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

2 x 109 x 403 x 134 x 639 = 7522586604

Therefore, the lowest common multiple of 218,403,268,639 is 7522586604.

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.

218 x 403 x 268 x 639 = 15045173208

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.

218 : 1, 2, 109, 218

403 : 1, 13, 31, 403

268 : 1, 2, 4, 67, 134, 268

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,403,268,639, is 1.

Now, the common factors can be found like this.

218:2x 109

403:13x 31

268:2x 2x 67

639:3x 3x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 15045173208/(1x2)

LCM = 15045173208/2

LCM = 7522586604

Thus, we can understand that the LCM of 218,403,268,639 is 7522586604.
