Given numbers are 779,660,346,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,660,346,505 is 8983568220.
Find LCM of 779,660,346,505 with Prime Factorization
| 2 | 779, 660, 346, 505 |
| 5 | 779, 330, 173, 505 |
| 779, 66, 173, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 779 x 66 x 173 x 101 = 8983568220
Therefore, the lowest common multiple of 779,660,346,505 is 8983568220.
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.
779 x 660 x 346 x 505 = 89835682200
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.
779 : 1, 19, 41, 779
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
346 : 1, 2, 173, 346
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,660,346,505, is 1.
Now, the common factors can be found like this.
779:19x 41
660:2x 2x 3x 5x 11
346:2x 173
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 89835682200/(1x10)
LCM = 89835682200/10
LCM = 8983568220
Thus, we can understand that the LCM of 779,660,346,505 is 8983568220.
