Given numbers are 624,575,120,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 624,575,120,939 is 112304400.
Find LCM of 624,575,120,939 with Prime Factorization
| 2 | 624, 575, 120, 939 |
| 2 | 312, 575, 60, 939 |
| 2 | 156, 575, 30, 939 |
| 3 | 78, 575, 15, 939 |
| 5 | 26, 575, 5, 313 |
| 26, 115, 1, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 26 x 115 x 1 x 313 = 112304400
Therefore, the lowest common multiple of 624,575,120,939 is 112304400.
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.
624 x 575 x 120 x 939 = 40429584000
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
575 : 1, 5, 23, 25, 115, 575
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,575,120,939, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
575:5x 5x 23
120:2x 2x 2x 3x 5
939:3x 313
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 40429584000/(1x360)
LCM = 40429584000/360
LCM = 112304400
Thus, we can understand that the LCM of 624,575,120,939 is 112304400.
