Given numbers are 146,646,171,365
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 146,646,171,365 is 2122110.
Find LCM of 146,646,171,365 with Prime Factorization
| 2 | 146, 646, 171, 365 |
| 19 | 73, 323, 171, 365 |
| 73 | 73, 17, 9, 365 |
| 1, 17, 9, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 73 x 1 x 17 x 9 x 5 = 2122110
Therefore, the lowest common multiple of 146,646,171,365 is 2122110.
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 646 x 171 x 365 = 5886733140
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
171 : 1, 3, 9, 19, 57, 171
365 : 1, 5, 73, 365
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 146,646,171,365, is 1.
Now, the common factors can be found like this.
146:2x 73
646:2x 17x 19
171:3x 3x 19
365:5x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 73 = 2774
Therefore, the value for common factors is 2774.
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 = 5886733140/(1x2774)
LCM = 5886733140/2774
LCM = 2122110
Thus, we can understand that the LCM of 146,646,171,365 is 2122110.
