Find LCM of 424,902,879,636,721 with Prime Factorization
| 2 | 424, 902, 879, 636, 721 |
| 2 | 212, 451, 879, 318, 721 |
| 3 | 106, 451, 879, 159, 721 |
| 53 | 106, 451, 293, 53, 721 |
| 2, 451, 293, 1, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 2 x 451 x 293 x 1 x 721 = 121189931016
Therefore, the lowest common multiple of 424,902,879,636,721 is 121189931016.
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.
424 x 902 x 879 x 636 x 721 = 154153592252352
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
902 : 1, 2, 11, 22, 41, 82, 451, 902
879 : 1, 3, 293, 879
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,902,879,636,721, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
902:2x 11x 41
879:3x 293
636:2x 2x 3x 53
721:7x 103
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 53 = 1272
Therefore, the value for common factors is 1272.
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 = 154153592252352/(1x1272)
LCM = 154153592252352/1272
LCM = 121189931016
Thus, we can understand that the LCM of 424,902,879,636,721 is 121189931016.
