Given numbers are 691,978,618,135

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

The LCM of 691,978,618,135 is 3132323730.

Find LCM of 691,978,618,135 with Prime Factorization

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

2 x 3 x 691 x 163 x 103 x 45 = 3132323730

Therefore, the lowest common multiple of 691,978,618,135 is 3132323730.

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.

691 x 978 x 618 x 135 = 56381827140

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.

691 : 1, 691

978 : 1, 2, 3, 6, 163, 326, 489, 978

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

135 : 1, 3, 5, 9, 15, 27, 45, 135

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,978,618,135, is 1.

Now, the common factors can be found like this.

691:691

978:2x 3x 163

618:2x 3x 103

135:3x 3x 3x 5

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 = 56381827140/(1x18)

LCM = 56381827140/18

LCM = 3132323730

Thus, we can understand that the LCM of 691,978,618,135 is 3132323730.
