Find LCM of 744,799,946,660 with Prime Factorization
| 2 | 744, 799, 946, 660 |
| 2 | 372, 799, 473, 330 |
| 3 | 186, 799, 473, 165 |
| 11 | 62, 799, 473, 55 |
| 62, 799, 43, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 62 x 799 x 43 x 5 = 1405888440
Therefore, the lowest common multiple of 744,799,946,660 is 1405888440.
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.
744 x 799 x 946 x 660 = 371154548160
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.
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
799 : 1, 17, 47, 799
946 : 1, 2, 11, 22, 43, 86, 473, 946
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 744,799,946,660, is 1.
Now, the common factors can be found like this.
744:2x 2x 2x 3x 31
799:17x 47
946:2x 11x 43
660:2x 2x 3x 5x 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 = 371154548160/(1x264)
LCM = 371154548160/264
LCM = 1405888440
Thus, we can understand that the LCM of 744,799,946,660 is 1405888440.
