Given numbers are 765,429,613,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,429,613,897 is 1542360105.
Find LCM of 765,429,613,897 with Prime Factorization
| 3 | 765, 429, 613, 897 |
| 13 | 255, 143, 613, 299 |
| 255, 11, 613, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 255 x 11 x 613 x 23 = 1542360105
Therefore, the lowest common multiple of 765,429,613,897 is 1542360105.
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 429 x 613 x 897 = 180456132285
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
613 : 1, 613
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,429,613,897, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
429:3x 11x 13
613:613
897:3x 13x 23
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 13 = 117
Therefore, the value for common factors is 117.
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 = 180456132285/(1x117)
LCM = 180456132285/117
LCM = 1542360105
Thus, we can understand that the LCM of 765,429,613,897 is 1542360105.
