Given numbers are 345,804,987,540

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

The LCM of 345,804,987,540 is 273774060.

Find LCM of 345,804,987,540 with Prime Factorization

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

2 x 2 x 3 x 5 x 23 x 67 x 329 x 9 = 273774060

Therefore, the lowest common multiple of 345,804,987,540 is 273774060.

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.

345 x 804 x 987 x 540 = 147837992400

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

987 : 1, 3, 7, 21, 47, 141, 329, 987

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,804,987,540, is 3.

Now, the common factors can be found like this.

345:3x 5x 23

804:2x 2x 3x 67

987:3x 7x 47

540:2x 2x 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 2x 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 147837992400/(3x180)

LCM = 147837992400/540

LCM = 273774060

Thus, we can understand that the LCM of 345,804,987,540 is 273774060.
