Find LCM of 169,432,648,989 with Prime Factorization
2 | 169, 432, 648, 989 |
2 | 169, 216, 324, 989 |
2 | 169, 108, 162, 989 |
3 | 169, 54, 81, 989 |
3 | 169, 18, 27, 989 |
3 | 169, 6, 9, 989 |
169, 2, 3, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 169 x 2 x 3 x 989 = 216614736
Therefore, the lowest common multiple of 169,432,648,989 is 216614736.
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 432 x 648 x 989 = 46788782976
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
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,432,648,989, is 1.
Now, the common factors can be found like this.
169:13x 13
432:2x 2x 2x 2x 3x 3x 3
648:2x 2x 2x 3x 3x 3x 3
989:23x 43
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 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 46788782976/(1x216)
LCM = 46788782976/216
LCM = 216614736
Thus, we can understand that the LCM of 169,432,648,989 is 216614736.
