Given numbers are 381,621,134,618

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

The LCM of 381,621,134,618 is 1088522334.

Find LCM of 381,621,134,618 with Prime Factorization

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

2 x 3 x 127 x 207 x 67 x 103 = 1088522334

Therefore, the lowest common multiple of 381,621,134,618 is 1088522334.

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.

381 x 621 x 134 x 618 = 19593402012

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.

381 : 1, 3, 127, 381

621 : 1, 3, 9, 23, 27, 69, 207, 621

134 : 1, 2, 67, 134

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 381,621,134,618, is 1.

Now, the common factors can be found like this.

381:3x 127

621:3x 3x 3x 23

134:2x 67

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 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 = 19593402012/(1x18)

LCM = 19593402012/18

LCM = 1088522334

Thus, we can understand that the LCM of 381,621,134,618 is 1088522334.
