Find LCM of 136,688,162,969 with Prime Factorization
2 | 136, 688, 162, 969 |
2 | 68, 344, 81, 969 |
2 | 34, 172, 81, 969 |
3 | 17, 86, 81, 969 |
17 | 17, 86, 27, 323 |
1, 86, 27, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 1 x 86 x 27 x 19 = 18000144
Therefore, the lowest common multiple of 136,688,162,969 is 18000144.
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.
136 x 688 x 162 x 969 = 14688117504
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.
136 : 1, 2, 4, 8, 17, 34, 68, 136
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,688,162,969, is 1.
Now, the common factors can be found like this.
136:2x 2x 2x 17
688:2x 2x 2x 2x 43
162:2x 3x 3x 3x 3
969:3x 17x 19
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 17 = 816
Therefore, the value for common factors is 816.
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 = 14688117504/(1x816)
LCM = 14688117504/816
LCM = 18000144
Thus, we can understand that the LCM of 136,688,162,969 is 18000144.
