The LCM of 468,860,721,851,168 is 123475028040.
Find LCM of 468,860,721,851,168 with Prime Factorization
| 2 | 468, 860, 721, 851, 168 |
| 2 | 234, 430, 721, 851, 84 |
| 3 | 117, 215, 721, 851, 42 |
| 7 | 39, 215, 721, 851, 14 |
| 39, 215, 103, 851, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 39 x 215 x 103 x 851 x 2 = 123475028040
Therefore, the lowest common multiple of 468,860,721,851,168 is 123475028040.
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.
468 x 860 x 721 x 851 x 168 = 41487609421440
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
721 : 1, 7, 103, 721
851 : 1, 23, 37, 851
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,860,721,851,168, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
860:2x 2x 5x 43
721:7x 103
851:23x 37
168:2x 2x 2x 3x 7
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 41487609421440/(1x336)
LCM = 41487609421440/336
LCM = 123475028040
Thus, we can understand that the LCM of 468,860,721,851,168 is 123475028040.
