Given numbers are 261,624,620,706

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

The LCM of 261,624,620,706 is 2970367920.

Find LCM of 261,624,620,706 with Prime Factorization

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

2 x 2 x 3 x 87 x 52 x 155 x 353 = 2970367920

Therefore, the lowest common multiple of 261,624,620,706 is 2970367920.

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.

261 x 624 x 620 x 706 = 71288830080

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.

261 : 1, 3, 9, 29, 87, 261

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

706 : 1, 2, 353, 706

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,624,620,706, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

624:2x 2x 2x 2x 3x 13

620:2x 2x 5x 31

706:2x 353

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

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 71288830080/(1x24)

LCM = 71288830080/24

LCM = 2970367920

Thus, we can understand that the LCM of 261,624,620,706 is 2970367920.
