Given numbers are 824,840,169,622,643

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

The LCM of 824,840,169,622,643 is 2923981209240.

Find LCM of 824,840,169,622,643 with Prime Factorization

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

2 x 2 x 2 x 103 x 105 x 169 x 311 x 643 = 2923981209240

Therefore, the lowest common multiple of 824,840,169,622,643 is 2923981209240.

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.

824 x 840 x 169 x 622 x 643 = 46783699347840

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.

824 : 1, 2, 4, 8, 103, 206, 412, 824

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

169 : 1, 13, 169

622 : 1, 2, 311, 622

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,840,169,622,643, is 1.

Now, the common factors can be found like this.

824:2x 2x 2x 103

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

169:13x 13

622:2x 311

643:643

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 2 = 16

Therefore, the value for common factors is 16.

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 = 46783699347840/(1x16)

LCM = 46783699347840/16

LCM = 2923981209240

Thus, we can understand that the LCM of 824,840,169,622,643 is 2923981209240.
