Find LCM of 460,391,690,363,632 with Prime Factorization
| 2 | 460, 391, 690, 363, 632 |
| 2 | 230, 391, 345, 363, 316 |
| 3 | 115, 391, 345, 363, 158 |
| 5 | 115, 391, 115, 121, 158 |
| 23 | 23, 391, 23, 121, 158 |
| 1, 17, 1, 121, 158 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 1 x 17 x 1 x 121 x 158 = 448508280
Therefore, the lowest common multiple of 460,391,690,363,632 is 448508280.
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.
460 x 391 x 690 x 363 x 632 = 28471305614400
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
391 : 1, 17, 23, 391
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
363 : 1, 3, 11, 33, 121, 363
632 : 1, 2, 4, 8, 79, 158, 316, 632
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,391,690,363,632, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
391:17x 23
690:2x 3x 5x 23
363:3x 11x 11
632:2x 2x 2x 79
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 5x 23x 23 = 63480
Therefore, the value for common factors is 63480.
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 = 28471305614400/(1x63480)
LCM = 28471305614400/63480
LCM = 448508280
Thus, we can understand that the LCM of 460,391,690,363,632 is 448508280.
