Given numbers are 645,703,554,912

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

The LCM of 645,703,554,912 is 2009623920.

Find LCM of 645,703,554,912 with Prime Factorization

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

2 x 3 x 19 x 215 x 37 x 277 x 8 = 2009623920

Therefore, the lowest common multiple of 645,703,554,912 is 2009623920.

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.

645 x 703 x 554 x 912 = 229097126880

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

703 : 1, 19, 37, 703

554 : 1, 2, 277, 554

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,703,554,912, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

703:19x 37

554:2x 277

912:2x 2x 2x 2x 3x 19

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 19 = 114

Therefore, the value for common factors is 114.

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 = 229097126880/(1x114)

LCM = 229097126880/114

LCM = 2009623920

Thus, we can understand that the LCM of 645,703,554,912 is 2009623920.
