Given numbers are 561,278,634,776,457

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

The LCM of 561,278,634,776,457 is 8766270046776.

Find LCM of 561,278,634,776,457 with Prime Factorization

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

2 x 561 x 139 x 317 x 388 x 457 = 8766270046776

Therefore, the lowest common multiple of 561,278,634,776,457 is 8766270046776.

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 278 x 634 x 776 x 457 = 35065080187104

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

278 : 1, 2, 139, 278

634 : 1, 2, 317, 634

776 : 1, 2, 4, 8, 97, 194, 388, 776

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,278,634,776,457, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

278:2x 139

634:2x 317

776:2x 2x 2x 97

457:457

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 35065080187104/(1x4)

LCM = 35065080187104/4

LCM = 8766270046776

Thus, we can understand that the LCM of 561,278,634,776,457 is 8766270046776.
