The LCM of 169,276,468,991 is 138672612.
Find LCM of 169,276,468,991 with Prime Factorization
| 2 | 169, 276, 468, 991 |
| 2 | 169, 138, 234, 991 |
| 3 | 169, 69, 117, 991 |
| 13 | 169, 23, 39, 991 |
| 13, 23, 3, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 13 x 23 x 3 x 991 = 138672612
Therefore, the lowest common multiple of 169,276,468,991 is 138672612.
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.
169 x 276 x 468 x 991 = 21632927472
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.
169 : 1, 13, 169
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,276,468,991, is 1.
Now, the common factors can be found like this.
169:13x 13
276:2x 2x 3x 23
468:2x 2x 3x 3x 13
991:991
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 21632927472/(1x156)
LCM = 21632927472/156
LCM = 138672612
Thus, we can understand that the LCM of 169,276,468,991 is 138672612.
