Given numbers are 560,380,988,298
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 560,380,988,298 is 20609680.
Find LCM of 560,380,988,298 with Prime Factorization
| 2 | 560, 380, 988, 298 |
| 2 | 280, 190, 494, 149 |
| 5 | 140, 95, 247, 149 |
| 19 | 28, 19, 247, 149 |
| 28, 1, 13, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 28 x 1 x 13 x 149 = 20609680
Therefore, the lowest common multiple of 560,380,988,298 is 20609680.
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.
560 x 380 x 988 x 298 = 62653427200
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
298 : 1, 2, 149, 298
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,380,988,298, is 2.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
380:2x 2x 5x 19
988:2x 2x 13x 19
298:2x 149
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 2x 5x 19 = 1520
Therefore, the value for common factors is 1520.
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 = 62653427200/(2x1520)
LCM = 62653427200/3040
LCM = 20609680
Thus, we can understand that the LCM of 560,380,988,298 is 20609680.
