Given numbers are 840,816,517,246,741

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

The LCM of 840,816,517,246,741 is 149530421040.

Find LCM of 840,816,517,246,741 with Prime Factorization

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

2 x 2 x 2 x 3 x 35 x 34 x 517 x 41 x 247 = 149530421040

Therefore, the lowest common multiple of 840,816,517,246,741 is 149530421040.

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.

840 x 816 x 517 x 246 x 741 = 64597141889280

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

517 : 1, 11, 47, 517

246 : 1, 2, 3, 6, 41, 82, 123, 246

741 : 1, 3, 13, 19, 39, 57, 247, 741

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,816,517,246,741, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

816:2x 2x 2x 2x 3x 17

517:11x 47

246:2x 3x 41

741:3x 13x 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 2x 2x 2x 3x 3x 3 = 432

Therefore, the value for common factors is 432.

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 = 64597141889280/(1x432)

LCM = 64597141889280/432

LCM = 149530421040

Thus, we can understand that the LCM of 840,816,517,246,741 is 149530421040.
