The LCM of 488,754,638,464 is 4047472.
Find LCM of 488,754,638,464 with Prime Factorization
| 2 | 488, 754, 638, 464 |
| 2 | 244, 377, 319, 232 |
| 2 | 122, 377, 319, 116 |
| 29 | 61, 377, 319, 58 |
| 61, 13, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 29 x 61 x 13 x 11 x 2 = 4047472
Therefore, the lowest common multiple of 488,754,638,464 is 4047472.
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.
488 x 754 x 638 x 464 = 108925566464
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.
488 : 1, 2, 4, 8, 61, 122, 244, 488
754 : 1, 2, 13, 26, 29, 58, 377, 754
638 : 1, 2, 11, 22, 29, 58, 319, 638
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,754,638,464, is 2.
Now, the common factors can be found like this.
488:2x 2x 2x 61
754:2x 13x 29
638:2x 11x 29
464:2x 2x 2x 2x 29
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 2x 29x 29 = 13456
Therefore, the value for common factors is 13456.
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 = 108925566464/(2x13456)
LCM = 108925566464/26912
LCM = 4047472
Thus, we can understand that the LCM of 488,754,638,464 is 4047472.
