Find LCM of 699,779,608,439,820 with Prime Factorization
| 2 | 699, 779, 608, 439, 820 |
| 2 | 699, 779, 304, 439, 410 |
| 19 | 699, 779, 152, 439, 205 |
| 41 | 699, 41, 8, 439, 205 |
| 699, 1, 8, 439, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 41 x 699 x 1 x 8 x 439 x 5 = 38247155040
Therefore, the lowest common multiple of 699,779,608,439,820 is 38247155040.
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.
699 x 779 x 608 x 439 x 820 = 119178135104640
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.
699 : 1, 3, 233, 699
779 : 1, 19, 41, 779
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
439 : 1, 439
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,779,608,439,820, is 1.
Now, the common factors can be found like this.
699:3x 233
779:19x 41
608:2x 2x 2x 2x 2x 19
439:439
820:2x 2x 5x 41
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 19x 41 = 3116
Therefore, the value for common factors is 3116.
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 = 119178135104640/(1x3116)
LCM = 119178135104640/3116
LCM = 38247155040
Thus, we can understand that the LCM of 699,779,608,439,820 is 38247155040.
