Given numbers are 7,504,989,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,504,989,575 is 12461400.
Find LCM of 7,504,989,575 with Prime Factorization
| 7 | 7, 504, 989, 575 |
| 23 | 1, 72, 989, 575 |
| 1, 72, 43, 25 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 1 x 72 x 43 x 25 = 12461400
Therefore, the lowest common multiple of 7,504,989,575 is 12461400.
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.
7 x 504 x 989 x 575 = 2006285400
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.
7 : 1, 7
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
989 : 1, 23, 43, 989
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,504,989,575, is 1.
Now, the common factors can be found like this.
7:7
504:2x 2x 2x 3x 3x 7
989:23x 43
575:5x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 2006285400/(1x161)
LCM = 2006285400/161
LCM = 12461400
Thus, we can understand that the LCM of 7,504,989,575 is 12461400.
