Given numbers are 691,534,559,688,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,534,559,688,315 is 173264822640.
Find LCM of 691,534,559,688,315 with Prime Factorization
| 2 | 691, 534, 559, 688, 315 |
| 3 | 691, 267, 559, 344, 315 |
| 43 | 691, 89, 559, 344, 105 |
| 691, 89, 13, 8, 105 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 691 x 89 x 13 x 8 x 105 = 173264822640
Therefore, the lowest common multiple of 691,534,559,688,315 is 173264822640.
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.
691 x 534 x 559 x 688 x 315 = 44702324241120
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.
691 : 1, 691
534 : 1, 2, 3, 6, 89, 178, 267, 534
559 : 1, 13, 43, 559
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,534,559,688,315, is 1.
Now, the common factors can be found like this.
691:691
534:2x 3x 89
559:13x 43
688:2x 2x 2x 2x 43
315:3x 3x 5x 7
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 43 = 258
Therefore, the value for common factors is 258.
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 = 44702324241120/(1x258)
LCM = 44702324241120/258
LCM = 173264822640
Thus, we can understand that the LCM of 691,534,559,688,315 is 173264822640.
