Given numbers are 103,310,489,489

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

The LCM of 103,310,489,489 is 15613770.

Find LCM of 103,310,489,489 with Prime Factorization

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

3 x 163 x 103 x 310 x 1 x 1 = 15613770

Therefore, the lowest common multiple of 103,310,489,489 is 15613770.

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.

103 x 310 x 489 x 489 = 7635133530

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.

103 : 1, 103

310 : 1, 2, 5, 10, 31, 62, 155, 310

489 : 1, 3, 163, 489

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,310,489,489, is 1.

Now, the common factors can be found like this.

103:103

310:2x 5x 31

489:3x 163

489:3x 163

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

3x 163 = 489

Therefore, the value for common factors is 489.

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 = 7635133530/(1x489)

LCM = 7635133530/489

LCM = 15613770

Thus, we can understand that the LCM of 103,310,489,489 is 15613770.
