Given numbers are 741,899,986,451,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,899,986,451,220 is 102148821060.
Find LCM of 741,899,986,451,220 with Prime Factorization
| 2 | 741, 899, 986, 451, 220 |
| 11 | 741, 899, 493, 451, 110 |
| 29 | 741, 899, 493, 41, 10 |
| 741, 31, 17, 41, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 741 x 31 x 17 x 41 x 10 = 102148821060
Therefore, the lowest common multiple of 741,899,986,451,220 is 102148821060.
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.
741 x 899 x 986 x 451 x 220 = 65170947836280
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
899 : 1, 29, 31, 899
986 : 1, 2, 17, 29, 34, 58, 493, 986
451 : 1, 11, 41, 451
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,899,986,451,220, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
899:29x 31
986:2x 17x 29
451:11x 41
220:2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 29 = 638
Therefore, the value for common factors is 638.
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 = 65170947836280/(1x638)
LCM = 65170947836280/638
LCM = 102148821060
Thus, we can understand that the LCM of 741,899,986,451,220 is 102148821060.
