Given numbers are 496,769,840,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 496,769,840,120 is 40049520.
Find LCM of 496,769,840,120 with Prime Factorization
| 2 | 496, 769, 840, 120 |
| 2 | 248, 769, 420, 60 |
| 2 | 124, 769, 210, 30 |
| 3 | 62, 769, 105, 15 |
| 5 | 62, 769, 35, 5 |
| 62, 769, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 62 x 769 x 7 x 1 = 40049520
Therefore, the lowest common multiple of 496,769,840,120 is 40049520.
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 769 x 840 x 120 = 38447539200
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
769 : 1, 769
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,769,840,120, is 1.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
769:769
840:2x 2x 2x 3x 5x 7
120:2x 2x 2x 3x 5
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 2x 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 38447539200/(1x960)
LCM = 38447539200/960
LCM = 40049520
Thus, we can understand that the LCM of 496,769,840,120 is 40049520.
