Given numbers are 684,128,100,993,148
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,128,100,993,148 is 6701558400.
Find LCM of 684,128,100,993,148 with Prime Factorization
| 2 | 684, 128, 100, 993, 148 |
| 2 | 342, 64, 50, 993, 74 |
| 3 | 171, 32, 25, 993, 37 |
| 57, 32, 25, 331, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 57 x 32 x 25 x 331 x 37 = 6701558400
Therefore, the lowest common multiple of 684,128,100,993,148 is 6701558400.
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.
684 x 128 x 100 x 993 x 148 = 1286699212800
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
128 : 1, 2, 4, 8, 16, 32, 64, 128
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
993 : 1, 3, 331, 993
148 : 1, 2, 4, 37, 74, 148
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,128,100,993,148, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
128:2x 2x 2x 2x 2x 2x 2
100:2x 2x 5x 5
993:3x 331
148:2x 2x 37
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 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 1286699212800/(1x192)
LCM = 1286699212800/192
LCM = 6701558400
Thus, we can understand that the LCM of 684,128,100,993,148 is 6701558400.
