Given numbers are 457,100,560,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,100,560,868 is 39667600.
Find LCM of 457,100,560,868 with Prime Factorization
| 2 | 457, 100, 560, 868 |
| 2 | 457, 50, 280, 434 |
| 5 | 457, 25, 140, 217 |
| 7 | 457, 5, 28, 217 |
| 457, 5, 4, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 457 x 5 x 4 x 31 = 39667600
Therefore, the lowest common multiple of 457,100,560,868 is 39667600.
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.
457 x 100 x 560 x 868 = 22213856000
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.
457 : 1, 457
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,100,560,868, is 1.
Now, the common factors can be found like this.
457:457
100:2x 2x 5x 5
560:2x 2x 2x 2x 5x 7
868:2x 2x 7x 31
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 2x 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 22213856000/(1x560)
LCM = 22213856000/560
LCM = 39667600
Thus, we can understand that the LCM of 457,100,560,868 is 39667600.
