Given numbers are 207,261,344,630,978

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

The LCM of 207,261,344,630,978 is 11781007560.

Find LCM of 207,261,344,630,978 with Prime Factorization

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

2 x 3 x 3 x 23 x 29 x 172 x 35 x 163 = 11781007560

Therefore, the lowest common multiple of 207,261,344,630,978 is 11781007560.

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.

207 x 261 x 344 x 630 x 978 = 11451139348320

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.

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

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

344 : 1, 2, 4, 8, 43, 86, 172, 344

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,261,344,630,978, is 1.

Now, the common factors can be found like this.

207:3x 3x 23

261:3x 3x 29

344:2x 2x 2x 43

630:2x 3x 3x 5x 7

978:2x 3x 163

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 3x 3x 3x 3 = 972

Therefore, the value for common factors is 972.

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 = 11451139348320/(1x972)

LCM = 11451139348320/972

LCM = 11781007560

Thus, we can understand that the LCM of 207,261,344,630,978 is 11781007560.
