Given numbers are 665,635,260,420,207

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

The LCM of 665,635,260,420,207 is 909073620.

Find LCM of 665,635,260,420,207 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 19 x 127 x 13 x 1 x 69 = 909073620

Therefore, the lowest common multiple of 665,635,260,420,207 is 909073620.

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.

665 x 635 x 260 x 420 x 207 = 9545273010000

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

635 : 1, 5, 127, 635

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

207 : 1, 3, 9, 23, 69, 207

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,635,260,420,207, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

635:5x 127

260:2x 2x 5x 13

420:2x 2x 3x 5x 7

207:3x 3x 23

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 5x 5x 7 = 10500

Therefore, the value for common factors is 10500.

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 = 9545273010000/(1x10500)

LCM = 9545273010000/10500

LCM = 909073620

Thus, we can understand that the LCM of 665,635,260,420,207 is 909073620.
