Given numbers are 489,722,871,428,618

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

The LCM of 489,722,871,428,618 is 6778212963756.

Find LCM of 489,722,871,428,618 with Prime Factorization

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

2 x 3 x 163 x 361 x 871 x 214 x 103 = 6778212963756

Therefore, the lowest common multiple of 489,722,871,428,618 is 6778212963756.

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.

489 x 722 x 871 x 428 x 618 = 81338555565072

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.

489 : 1, 3, 163, 489

722 : 1, 2, 19, 38, 361, 722

871 : 1, 13, 67, 871

428 : 1, 2, 4, 107, 214, 428

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 489,722,871,428,618, is 1.

Now, the common factors can be found like this.

489:3x 163

722:2x 19x 19

871:13x 67

428:2x 2x 107

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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 81338555565072/(1x12)

LCM = 81338555565072/12

LCM = 6778212963756

Thus, we can understand that the LCM of 489,722,871,428,618 is 6778212963756.
