Given numbers are 380,710,290,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,710,290,247 is 10171460.
Find LCM of 380,710,290,247 with Prime Factorization
| 2 | 380, 710, 290, 247 |
| 5 | 190, 355, 145, 247 |
| 19 | 38, 71, 29, 247 |
| 2, 71, 29, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 2 x 71 x 29 x 13 = 10171460
Therefore, the lowest common multiple of 380,710,290,247 is 10171460.
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.
380 x 710 x 290 x 247 = 19325774000
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
710 : 1, 2, 5, 10, 71, 142, 355, 710
290 : 1, 2, 5, 10, 29, 58, 145, 290
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,710,290,247, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
710:2x 5x 71
290:2x 5x 29
247:13x 19
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 5x 5x 19 = 1900
Therefore, the value for common factors is 1900.
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 = 19325774000/(1x1900)
LCM = 19325774000/1900
LCM = 10171460
Thus, we can understand that the LCM of 380,710,290,247 is 10171460.
