Find LCM of 525,789,430,138,287 with Prime Factorization
| 2 | 525, 789, 430, 138, 287 |
| 3 | 525, 789, 215, 69, 287 |
| 5 | 175, 263, 215, 23, 287 |
| 7 | 35, 263, 43, 23, 287 |
| 5, 263, 43, 23, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 5 x 263 x 43 x 23 x 41 = 11197606350
Therefore, the lowest common multiple of 525,789,430,138,287 is 11197606350.
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.
525 x 789 x 430 x 138 x 287 = 7054492000500
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.
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
789 : 1, 3, 263, 789
430 : 1, 2, 5, 10, 43, 86, 215, 430
138 : 1, 2, 3, 6, 23, 46, 69, 138
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,789,430,138,287, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
789:3x 263
430:2x 5x 43
138:2x 3x 23
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 7054492000500/(1x630)
LCM = 7054492000500/630
LCM = 11197606350
Thus, we can understand that the LCM of 525,789,430,138,287 is 11197606350.
