Given numbers are 843,720,654,918

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

The LCM of 843,720,654,918 is 1124696880.

Find LCM of 843,720,654,918 with Prime Factorization

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

2 x 3 x 3 x 281 x 40 x 109 x 51 = 1124696880

Therefore, the lowest common multiple of 843,720,654,918 is 1124696880.

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.

843 x 720 x 654 x 918 = 364401789120

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.

843 : 1, 3, 281, 843

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

654 : 1, 2, 3, 6, 109, 218, 327, 654

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,720,654,918, is 3.

Now, the common factors can be found like this.

843:3x 281

720:2x 2x 2x 2x 3x 3x 5

654:2x 3x 109

918:2x 3x 3x 3x 17

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 3 = 108

Therefore, the value for common factors is 108.

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 = 364401789120/(3x108)

LCM = 364401789120/324

LCM = 1124696880

Thus, we can understand that the LCM of 843,720,654,918 is 1124696880.
