Given numbers are 668,551,758,861

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

The LCM of 668,551,758,861 is 120107581692.

Find LCM of 668,551,758,861 with Prime Factorization

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

2 x 334 x 551 x 379 x 861 = 120107581692

Therefore, the lowest common multiple of 668,551,758,861 is 120107581692.

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.

668 x 551 x 758 x 861 = 240215163384

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.

668 : 1, 2, 4, 167, 334, 668

551 : 1, 19, 29, 551

758 : 1, 2, 379, 758

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,551,758,861, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

551:19x 29

758:2x 379

861:3x 7x 41

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

2 = 2

Therefore, the value for common factors is 2.

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 = 240215163384/(1x2)

LCM = 240215163384/2

LCM = 120107581692

Thus, we can understand that the LCM of 668,551,758,861 is 120107581692.
