Given numbers are 745,207,920,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,207,920,779 is 961067880.
Find LCM of 745,207,920,779 with Prime Factorization
5 | 745, 207, 920, 779 |
23 | 149, 207, 184, 779 |
149, 9, 8, 779 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 149 x 9 x 8 x 779 = 961067880
Therefore, the lowest common multiple of 745,207,920,779 is 961067880.
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.
745 x 207 x 920 x 779 = 110522806200
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.
745 : 1, 5, 149, 745
207 : 1, 3, 9, 23, 69, 207
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,207,920,779, is 1.
Now, the common factors can be found like this.
745:5x 149
207:3x 3x 23
920:2x 2x 2x 5x 23
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 110522806200/(1x115)
LCM = 110522806200/115
LCM = 961067880
Thus, we can understand that the LCM of 745,207,920,779 is 961067880.
