Given numbers are 910,822,720,561

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

The LCM of 910,822,720,561 is 1678556880.

Find LCM of 910,822,720,561 with Prime Factorization

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

2 x 3 x 5 x 91 x 137 x 24 x 187 = 1678556880

Therefore, the lowest common multiple of 910,822,720,561 is 1678556880.

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.

910 x 822 x 720 x 561 = 302140238400

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.

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

822 : 1, 2, 3, 6, 137, 274, 411, 822

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,822,720,561, is 1.

Now, the common factors can be found like this.

910:2x 5x 7x 13

822:2x 3x 137

720:2x 2x 2x 2x 3x 3x 5

561:3x 11x 17

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 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 302140238400/(1x180)

LCM = 302140238400/180

LCM = 1678556880

Thus, we can understand that the LCM of 910,822,720,561 is 1678556880.
