Given numbers are 765,561,207,514
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,561,207,514 is 99482130.
Find LCM of 765,561,207,514 with Prime Factorization
| 3 | 765, 561, 207, 514 |
| 3 | 255, 187, 69, 514 |
| 17 | 85, 187, 23, 514 |
| 5, 11, 23, 514 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 5 x 11 x 23 x 514 = 99482130
Therefore, the lowest common multiple of 765,561,207,514 is 99482130.
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.
765 x 561 x 207 x 514 = 45662297670
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
561 : 1, 3, 11, 17, 33, 51, 187, 561
207 : 1, 3, 9, 23, 69, 207
514 : 1, 2, 257, 514
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,561,207,514, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
561:3x 11x 17
207:3x 3x 23
514:2x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 45662297670/(1x459)
LCM = 45662297670/459
LCM = 99482130
Thus, we can understand that the LCM of 765,561,207,514 is 99482130.
