Given numbers are 978,104,294,156
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,104,294,156 is 2491944.
Find LCM of 978,104,294,156 with Prime Factorization
| 2 | 978, 104, 294, 156 |
| 2 | 489, 52, 147, 78 |
| 3 | 489, 26, 147, 39 |
| 13 | 163, 26, 49, 13 |
| 163, 2, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 163 x 2 x 49 x 1 = 2491944
Therefore, the lowest common multiple of 978,104,294,156 is 2491944.
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.
978 x 104 x 294 x 156 = 4664919168
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
104 : 1, 2, 4, 8, 13, 26, 52, 104
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,104,294,156, is 2.
Now, the common factors can be found like this.
978:2x 3x 163
104:2x 2x 2x 13
294:2x 3x 7x 7
156:2x 2x 3x 13
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 13 = 936
Therefore, the value for common factors is 936.
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 = 4664919168/(2x936)
LCM = 4664919168/1872
LCM = 2491944
Thus, we can understand that the LCM of 978,104,294,156 is 2491944.
