Given numbers are 561,944,649,161

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

The LCM of 561,944,649,161 is 85263024.

Find LCM of 561,944,649,161 with Prime Factorization

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

11 x 59 x 51 x 16 x 1 x 161 = 85263024

Therefore, the lowest common multiple of 561,944,649,161 is 85263024.

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.

561 x 944 x 649 x 161 = 55335702576

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.

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

944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944

649 : 1, 11, 59, 649

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,944,649,161, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

944:2x 2x 2x 2x 59

649:11x 59

161:7x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

11x 59 = 649

Therefore, the value for common factors is 649.

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 = 55335702576/(1x649)

LCM = 55335702576/649

LCM = 85263024

Thus, we can understand that the LCM of 561,944,649,161 is 85263024.
