Given numbers are 561,440,553,787

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

The LCM of 561,440,553,787 is 9766134840.

Find LCM of 561,440,553,787 with Prime Factorization

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

11 x 51 x 40 x 553 x 787 = 9766134840

Therefore, the lowest common multiple of 561,440,553,787 is 9766134840.

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 440 x 553 x 787 = 107427483240

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

553 : 1, 7, 79, 553

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,440,553,787, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

440:2x 2x 2x 5x 11

553:7x 79

787:787

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

11 = 11

Therefore, the value for common factors is 11.

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 = 107427483240/(1x11)

LCM = 107427483240/11

LCM = 9766134840

Thus, we can understand that the LCM of 561,440,553,787 is 9766134840.
