The LCM of 315,440,463,209,938 is 16338140280.
Find LCM of 315,440,463,209,938 with Prime Factorization
| 2 | 315, 440, 463, 209, 938 |
| 5 | 315, 220, 463, 209, 469 |
| 7 | 63, 44, 463, 209, 469 |
| 11 | 9, 44, 463, 209, 67 |
| 9, 4, 463, 19, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 9 x 4 x 463 x 19 x 67 = 16338140280
Therefore, the lowest common multiple of 315,440,463,209,938 is 16338140280.
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.
315 x 440 x 463 x 209 x 938 = 12580368015600
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
463 : 1, 463
209 : 1, 11, 19, 209
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,440,463,209,938, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
440:2x 2x 2x 5x 11
463:463
209:11x 19
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 12580368015600/(1x770)
LCM = 12580368015600/770
LCM = 16338140280
Thus, we can understand that the LCM of 315,440,463,209,938 is 16338140280.
