Given numbers are 103,158,316,978,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,158,316,978,786 is 2084992332.
Find LCM of 103,158,316,978,786 with Prime Factorization
| 2 | 103, 158, 316, 978, 786 |
| 3 | 103, 79, 158, 489, 393 |
| 79 | 103, 79, 158, 163, 131 |
| 103, 1, 2, 163, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 79 x 103 x 1 x 2 x 163 x 131 = 2084992332
Therefore, the lowest common multiple of 103,158,316,978,786 is 2084992332.
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.
103 x 158 x 316 x 978 x 786 = 3953145461472
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.
103 : 1, 103
158 : 1, 2, 79, 158
316 : 1, 2, 4, 79, 158, 316
978 : 1, 2, 3, 6, 163, 326, 489, 978
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,158,316,978,786, is 1.
Now, the common factors can be found like this.
103:103
158:2x 79
316:2x 2x 79
978:2x 3x 163
786:2x 3x 131
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 79 = 1896
Therefore, the value for common factors is 1896.
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 = 3953145461472/(1x1896)
LCM = 3953145461472/1896
LCM = 2084992332
Thus, we can understand that the LCM of 103,158,316,978,786 is 2084992332.
