Find LCM of 456,928,781,749,891 with Prime Factorization
| 2 | 456, 928, 781, 749, 891 |
| 2 | 228, 464, 781, 749, 891 |
| 2 | 114, 232, 781, 749, 891 |
| 3 | 57, 116, 781, 749, 891 |
| 11 | 19, 116, 781, 749, 297 |
| 19, 116, 71, 749, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 19 x 116 x 71 x 749 x 27 = 835448046048
Therefore, the lowest common multiple of 456,928,781,749,891 is 835448046048.
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.
456 x 928 x 781 x 749 x 891 = 220558284156672
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
781 : 1, 11, 71, 781
749 : 1, 7, 107, 749
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,928,781,749,891, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
928:2x 2x 2x 2x 2x 29
781:11x 71
749:7x 107
891:3x 3x 3x 3x 11
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 220558284156672/(1x264)
LCM = 220558284156672/264
LCM = 835448046048
Thus, we can understand that the LCM of 456,928,781,749,891 is 835448046048.
