Given numbers are 561,717,454,426

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

The LCM of 561,717,454,426 is 4321902486.

Find LCM of 561,717,454,426 with Prime Factorization

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

2 x 3 x 187 x 239 x 227 x 71 = 4321902486

Therefore, the lowest common multiple of 561,717,454,426 is 4321902486.

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 717 x 454 x 426 = 77794244748

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

717 : 1, 3, 239, 717

454 : 1, 2, 227, 454

426 : 1, 2, 3, 6, 71, 142, 213, 426

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,717,454,426, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

717:3x 239

454:2x 227

426:2x 3x 71

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 77794244748/(1x18)

LCM = 77794244748/18

LCM = 4321902486

Thus, we can understand that the LCM of 561,717,454,426 is 4321902486.
