Given numbers are 561,107,739,840,791

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

The LCM of 561,107,739,840,791 is 1403548912920.

Find LCM of 561,107,739,840,791 with Prime Factorization

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

3 x 7 x 187 x 107 x 739 x 40 x 113 = 1403548912920

Therefore, the lowest common multiple of 561,107,739,840,791 is 1403548912920.

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 107 x 739 x 840 x 791 = 29474527171320

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

107 : 1, 107

739 : 1, 739

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,107,739,840,791, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

107:107

739:739

840:2x 2x 2x 3x 5x 7

791:7x 113

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 29474527171320/(1x21)

LCM = 29474527171320/21

LCM = 1403548912920

Thus, we can understand that the LCM of 561,107,739,840,791 is 1403548912920.
