Given numbers are 170,260,253,412,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 170,260,253,412,387 is 44574961860.
Find LCM of 170,260,253,412,387 with Prime Factorization
| 2 | 170, 260, 253, 412, 387 |
| 2 | 85, 130, 253, 206, 387 |
| 5 | 85, 65, 253, 103, 387 |
| 17, 13, 253, 103, 387 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 13 x 253 x 103 x 387 = 44574961860
Therefore, the lowest common multiple of 170,260,253,412,387 is 44574961860.
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.
170 x 260 x 253 x 412 x 387 = 1782998474400
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
253 : 1, 11, 23, 253
412 : 1, 2, 4, 103, 206, 412
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,260,253,412,387, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
260:2x 2x 5x 13
253:11x 23
412:2x 2x 103
387:3x 3x 43
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 5 = 40
Therefore, the value for common factors is 40.
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 = 1782998474400/(1x40)
LCM = 1782998474400/40
LCM = 44574961860
Thus, we can understand that the LCM of 170,260,253,412,387 is 44574961860.
