Find LCM of 496,108,162,240,778 with Prime Factorization
| 2 | 496, 108, 162, 240, 778 |
| 2 | 248, 54, 81, 120, 389 |
| 2 | 124, 27, 81, 60, 389 |
| 2 | 62, 27, 81, 30, 389 |
| 3 | 31, 27, 81, 15, 389 |
| 3 | 31, 9, 27, 5, 389 |
| 3 | 31, 3, 9, 5, 389 |
| 31, 1, 3, 5, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 3 x 31 x 1 x 3 x 5 x 389 = 78142320
Therefore, the lowest common multiple of 496,108,162,240,778 is 78142320.
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 108 x 162 x 240 x 778 = 1620359147520
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
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
778 : 1, 2, 389, 778
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,108,162,240,778, is 2.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
108:2x 2x 3x 3x 3
162:2x 3x 3x 3x 3
240:2x 2x 2x 2x 3x 5
778:2x 389
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 2x 3x 3x 3x 3 = 10368
Therefore, the value for common factors is 10368.
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 = 1620359147520/(2x10368)
LCM = 1620359147520/20736
LCM = 78142320
Thus, we can understand that the LCM of 496,108,162,240,778 is 78142320.
