Given numbers are 660,910,638,306

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

The LCM of 660,910,638,306 is 88828740.

Find LCM of 660,910,638,306 with Prime Factorization

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

2 x 3 x 5 x 11 x 2 x 91 x 29 x 51 = 88828740

Therefore, the lowest common multiple of 660,910,638,306 is 88828740.

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.

660 x 910 x 638 x 306 = 117253936800

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

638 : 1, 2, 11, 22, 29, 58, 319, 638

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,910,638,306, is 2.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

910:2x 5x 7x 13

638:2x 11x 29

306:2x 3x 3x 17

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 3x 5x 11 = 660

Therefore, the value for common factors is 660.

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 = 117253936800/(2x660)

LCM = 117253936800/1320

LCM = 88828740

Thus, we can understand that the LCM of 660,910,638,306 is 88828740.
