Given numbers are 605,836,480,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,836,480,147 is 54072480.
Find LCM of 605,836,480,147 with Prime Factorization
| 2 | 605, 836, 480, 147 |
| 2 | 605, 418, 240, 147 |
| 3 | 605, 209, 120, 147 |
| 5 | 605, 209, 40, 49 |
| 11 | 121, 209, 8, 49 |
| 11, 19, 8, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 11 x 19 x 8 x 49 = 54072480
Therefore, the lowest common multiple of 605,836,480,147 is 54072480.
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.
605 x 836 x 480 x 147 = 35687836800
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.
605 : 1, 5, 11, 55, 121, 605
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,836,480,147, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
836:2x 2x 11x 19
480:2x 2x 2x 2x 2x 3x 5
147:3x 7x 7
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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 35687836800/(1x660)
LCM = 35687836800/660
LCM = 54072480
Thus, we can understand that the LCM of 605,836,480,147 is 54072480.
