Given numbers are 545,120,872,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,120,872,862 is 5637480.
Find LCM of 545,120,872,862 with Prime Factorization
| 2 | 545, 120, 872, 862 |
| 2 | 545, 60, 436, 431 |
| 2 | 545, 30, 218, 431 |
| 5 | 545, 15, 109, 431 |
| 109 | 109, 3, 109, 431 |
| 1, 3, 1, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 109 x 1 x 3 x 1 x 431 = 5637480
Therefore, the lowest common multiple of 545,120,872,862 is 5637480.
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.
545 x 120 x 872 x 862 = 49158825600
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.
545 : 1, 5, 109, 545
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
872 : 1, 2, 4, 8, 109, 218, 436, 872
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,120,872,862, is 1.
Now, the common factors can be found like this.
545:5x 109
120:2x 2x 2x 3x 5
872:2x 2x 2x 109
862:2x 431
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 109 = 8720
Therefore, the value for common factors is 8720.
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 = 49158825600/(1x8720)
LCM = 49158825600/8720
LCM = 5637480
Thus, we can understand that the LCM of 545,120,872,862 is 5637480.
