Given numbers are 109,206,721,618

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

The LCM of 109,206,721,618 is 471534.

Find LCM of 109,206,721,618 with Prime Factorization

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

2 x 103 x 109 x 1 x 7 x 3 = 471534

Therefore, the lowest common multiple of 109,206,721,618 is 471534.

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.

109 x 206 x 721 x 618 = 10005008412

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.

109 : 1, 109

206 : 1, 2, 103, 206

721 : 1, 7, 103, 721

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 109,206,721,618, is 1.

Now, the common factors can be found like this.

109:109

206:2x 103

721:7x 103

618:2x 3x 103

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

2x 103x 103 = 21218

Therefore, the value for common factors is 21218.

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 = 10005008412/(1x21218)

LCM = 10005008412/21218

LCM = 471534

Thus, we can understand that the LCM of 109,206,721,618 is 471534.
