Given numbers are 102,618,138,975

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

The LCM of 102,618,138,975 is 78532350.

Find LCM of 102,618,138,975 with Prime Factorization

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

2 x 3 x 17 x 103 x 23 x 325 = 78532350

Therefore, the lowest common multiple of 102,618,138,975 is 78532350.

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.

102 x 618 x 138 x 975 = 8481493800

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.

102 : 1, 2, 3, 6, 17, 34, 51, 102

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,618,138,975, is 3.

Now, the common factors can be found like this.

102:2x 3x 17

618:2x 3x 103

138:2x 3x 23

975:3x 5x 5x 13

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 8481493800/(3x36)

LCM = 8481493800/108

LCM = 78532350

Thus, we can understand that the LCM of 102,618,138,975 is 78532350.
