Given numbers are 219,156,618,681

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

The LCM of 219,156,618,681 is 266262828.

Find LCM of 219,156,618,681 with Prime Factorization

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

2 x 3 x 73 x 26 x 103 x 227 = 266262828

Therefore, the lowest common multiple of 219,156,618,681 is 266262828.

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.

219 x 156 x 618 x 681 = 14378192712

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.

219 : 1, 3, 73, 219

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

618 : 1, 2, 3, 6, 103, 206, 309, 618

681 : 1, 3, 227, 681

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,156,618,681, is 3.

Now, the common factors can be found like this.

219:3x 73

156:2x 2x 3x 13

618:2x 3x 103

681:3x 227

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 14378192712/(3x18)

LCM = 14378192712/54

LCM = 266262828

Thus, we can understand that the LCM of 219,156,618,681 is 266262828.
