Find LCM of 762,399,779,984 with Prime Factorization
| 2 | 762, 399, 779, 984 |
| 3 | 381, 399, 779, 492 |
| 19 | 127, 133, 779, 164 |
| 41 | 127, 7, 41, 164 |
| 127, 7, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 41 x 127 x 7 x 1 x 4 = 16620744
Therefore, the lowest common multiple of 762,399,779,984 is 16620744.
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.
762 x 399 x 779 x 984 = 233056072368
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
399 : 1, 3, 7, 19, 21, 57, 133, 399
779 : 1, 19, 41, 779
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,399,779,984, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
399:3x 7x 19
779:19x 41
984:2x 2x 2x 3x 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 3x 3x 19x 41 = 14022
Therefore, the value for common factors is 14022.
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 = 233056072368/(1x14022)
LCM = 233056072368/14022
LCM = 16620744
Thus, we can understand that the LCM of 762,399,779,984 is 16620744.
