Given numbers are 484,490,139,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,490,139,395 is 1302126980.
Find LCM of 484,490,139,395 with Prime Factorization
| 2 | 484, 490, 139, 395 |
| 5 | 242, 245, 139, 395 |
| 242, 49, 139, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 242 x 49 x 139 x 79 = 1302126980
Therefore, the lowest common multiple of 484,490,139,395 is 1302126980.
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 139 x 395 = 13021269800
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
139 : 1, 139
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,490,139,395, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
490:2x 5x 7x 7
139:139
395:5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 13021269800/(1x10)
LCM = 13021269800/10
LCM = 1302126980
Thus, we can understand that the LCM of 484,490,139,395 is 1302126980.
