Find LCM of 747,876,920,856,752 with Prime Factorization
2 | 747, 876, 920, 856, 752 |
2 | 747, 438, 460, 428, 376 |
2 | 747, 219, 230, 214, 188 |
3 | 747, 219, 115, 107, 94 |
249, 73, 115, 107, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 249 x 73 x 115 x 107 x 94 = 504594974160
Therefore, the lowest common multiple of 747,876,920,856,752 is 504594974160.
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.
747 x 876 x 920 x 856 x 752 = 387528940154880
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.
747 : 1, 3, 9, 83, 249, 747
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
856 : 1, 2, 4, 8, 107, 214, 428, 856
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,876,920,856,752, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
876:2x 2x 3x 73
920:2x 2x 2x 5x 23
856:2x 2x 2x 107
752:2x 2x 2x 2x 47
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 2x 2x 2x 2x 2x 2x 3 = 768
Therefore, the value for common factors is 768.
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 = 387528940154880/(1x768)
LCM = 387528940154880/768
LCM = 504594974160
Thus, we can understand that the LCM of 747,876,920,856,752 is 504594974160.
