Given numbers are 455,568,871,690,740
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,568,871,690,740 is 44206420440.
Find LCM of 455,568,871,690,740 with Prime Factorization
| 2 | 455, 568, 871, 690, 740 |
| 2 | 455, 284, 871, 345, 370 |
| 5 | 455, 142, 871, 345, 185 |
| 13 | 91, 142, 871, 69, 37 |
| 7, 142, 67, 69, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 7 x 142 x 67 x 69 x 37 = 44206420440
Therefore, the lowest common multiple of 455,568,871,690,740 is 44206420440.
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.
455 x 568 x 871 x 690 x 740 = 114936693144000
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
568 : 1, 2, 4, 8, 71, 142, 284, 568
871 : 1, 13, 67, 871
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,568,871,690,740, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
568:2x 2x 2x 71
871:13x 67
690:2x 3x 5x 23
740:2x 2x 5x 37
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 5x 13 = 2600
Therefore, the value for common factors is 2600.
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 = 114936693144000/(1x2600)
LCM = 114936693144000/2600
LCM = 44206420440
Thus, we can understand that the LCM of 455,568,871,690,740 is 44206420440.
