Given numbers are 146,972,876,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 146,972,876,391 is 27743796.
Find LCM of 146,972,876,391 with Prime Factorization
2 | 146, 972, 876, 391 |
2 | 73, 486, 438, 391 |
3 | 73, 243, 219, 391 |
73 | 73, 81, 73, 391 |
1, 81, 1, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 73 x 1 x 81 x 1 x 391 = 27743796
Therefore, the lowest common multiple of 146,972,876,391 is 27743796.
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.
146 x 972 x 876 x 391 = 48607130592
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.
146 : 1, 2, 73, 146
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 146,972,876,391, is 1.
Now, the common factors can be found like this.
146:2x 73
972:2x 2x 3x 3x 3x 3x 3
876:2x 2x 3x 73
391:17x 23
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 73 = 1752
Therefore, the value for common factors is 1752.
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 = 48607130592/(1x1752)
LCM = 48607130592/1752
LCM = 27743796
Thus, we can understand that the LCM of 146,972,876,391 is 27743796.
