Given numbers are 496,754,667,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 496,754,667,390 is 64512240.
Find LCM of 496,754,667,390 with Prime Factorization
| 2 | 496, 754, 667, 390 |
| 13 | 248, 377, 667, 195 |
| 29 | 248, 29, 667, 15 |
| 248, 1, 23, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 248 x 1 x 23 x 15 = 64512240
Therefore, the lowest common multiple of 496,754,667,390 is 64512240.
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 754 x 667 x 390 = 97284457920
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
754 : 1, 2, 13, 26, 29, 58, 377, 754
667 : 1, 23, 29, 667
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,754,667,390, is 1.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
754:2x 13x 29
667:23x 29
390:2x 3x 5x 13
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 13x 29 = 1508
Therefore, the value for common factors is 1508.
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 = 97284457920/(1x1508)
LCM = 97284457920/1508
LCM = 64512240
Thus, we can understand that the LCM of 496,754,667,390 is 64512240.
