Given numbers are 496,620,478,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 496,620,478,315 is 37341360.
Find LCM of 496,620,478,315 with Prime Factorization
| 2 | 496, 620, 478, 315 |
| 2 | 248, 310, 239, 315 |
| 5 | 124, 155, 239, 315 |
| 31 | 124, 31, 239, 63 |
| 4, 1, 239, 63 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 31 x 4 x 1 x 239 x 63 = 37341360
Therefore, the lowest common multiple of 496,620,478,315 is 37341360.
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.
496 x 620 x 478 x 315 = 46303286400
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.
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
478 : 1, 2, 239, 478
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 496,620,478,315, is 1.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
620:2x 2x 5x 31
478:2x 239
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 2x 2x 5x 31 = 1240
Therefore, the value for common factors is 1240.
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 = 46303286400/(1x1240)
LCM = 46303286400/1240
LCM = 37341360
Thus, we can understand that the LCM of 496,620,478,315 is 37341360.
