Given numbers are 623,525,724,455,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,525,724,455,905 is 439775700.
Find LCM of 623,525,724,455,905 with Prime Factorization
| 5 | 623, 525, 724, 455, 905 |
| 7 | 623, 105, 724, 91, 181 |
| 181 | 89, 15, 724, 13, 181 |
| 89, 15, 4, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 181 x 89 x 15 x 4 x 13 x 1 = 439775700
Therefore, the lowest common multiple of 623,525,724,455,905 is 439775700.
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.
623 x 525 x 724 x 455 x 905 = 97509267082500
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.
623 : 1, 7, 89, 623
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
724 : 1, 2, 4, 181, 362, 724
455 : 1, 5, 7, 13, 35, 65, 91, 455
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,525,724,455,905, is 1.
Now, the common factors can be found like this.
623:7x 89
525:3x 5x 5x 7
724:2x 2x 181
455:5x 7x 13
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 7x 181 = 221725
Therefore, the value for common factors is 221725.
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 = 97509267082500/(1x221725)
LCM = 97509267082500/221725
LCM = 439775700
Thus, we can understand that the LCM of 623,525,724,455,905 is 439775700.
