Given numbers are 690,912,807,486

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

The LCM of 690,912,807,486 is 2285230320.

Find LCM of 690,912,807,486 with Prime Factorization

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

2 x 3 x 115 x 152 x 269 x 81 = 2285230320

Therefore, the lowest common multiple of 690,912,807,486 is 2285230320.

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.

690 x 912 x 807 x 486 = 246804874560

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

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

807 : 1, 3, 269, 807

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,912,807,486, is 3.

Now, the common factors can be found like this.

690:2x 3x 5x 23

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

807:3x 269

486:2x 3x 3x 3x 3x 3

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 = 246804874560/(3x36)

LCM = 246804874560/108

LCM = 2285230320

Thus, we can understand that the LCM of 690,912,807,486 is 2285230320.
