Given numbers are 690,432,841,726,894

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

The LCM of 690,432,841,726,894 is 753267485520.

Find LCM of 690,432,841,726,894 with Prime Factorization

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

2 x 3 x 115 x 72 x 841 x 121 x 149 = 753267485520

Therefore, the lowest common multiple of 690,432,841,726,894 is 753267485520.

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 432 x 841 x 726 x 894 = 162705776872320

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

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

841 : 1, 29, 841

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

894 : 1, 2, 3, 6, 149, 298, 447, 894

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,432,841,726,894, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

432:2x 2x 2x 2x 3x 3x 3

841:29x 29

726:2x 3x 11x 11

894:2x 3x 149

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 2x 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 162705776872320/(1x216)

LCM = 162705776872320/216

LCM = 753267485520

Thus, we can understand that the LCM of 690,432,841,726,894 is 753267485520.
