Given numbers are 484,490,760,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,490,760,994 is 319928840.
Find LCM of 484,490,760,994 with Prime Factorization
| 2 | 484, 490, 760, 994 |
| 2 | 242, 245, 380, 497 |
| 5 | 121, 245, 190, 497 |
| 7 | 121, 49, 38, 497 |
| 121, 7, 38, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 121 x 7 x 38 x 71 = 319928840
Therefore, the lowest common multiple of 484,490,760,994 is 319928840.
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.
484 x 490 x 760 x 994 = 179160150400
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
994 : 1, 2, 7, 14, 71, 142, 497, 994
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,490,760,994, is 2.
Now, the common factors can be found like this.
484:2x 2x 11x 11
490:2x 5x 7x 7
760:2x 2x 2x 5x 19
994:2x 7x 71
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 179160150400/(2x280)
LCM = 179160150400/560
LCM = 319928840
Thus, we can understand that the LCM of 484,490,760,994 is 319928840.
