Given numbers are 681,105,740,477
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,105,740,477 is 560885220.
Find LCM of 681,105,740,477 with Prime Factorization
| 3 | 681, 105, 740, 477 |
| 5 | 227, 35, 740, 159 |
| 227, 7, 148, 159 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 227 x 7 x 148 x 159 = 560885220
Therefore, the lowest common multiple of 681,105,740,477 is 560885220.
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.
681 x 105 x 740 x 477 = 25239834900
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.
681 : 1, 3, 227, 681
105 : 1, 3, 5, 7, 15, 21, 35, 105
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
477 : 1, 3, 9, 53, 159, 477
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,105,740,477, is 1.
Now, the common factors can be found like this.
681:3x 227
105:3x 5x 7
740:2x 2x 5x 37
477:3x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 25239834900/(1x45)
LCM = 25239834900/45
LCM = 560885220
Thus, we can understand that the LCM of 681,105,740,477 is 560885220.
