Find LCM of 456,968,455,858,248 with Prime Factorization
| 2 | 456, 968, 455, 858, 248 |
| 2 | 228, 484, 455, 429, 124 |
| 2 | 114, 242, 455, 429, 62 |
| 3 | 57, 121, 455, 429, 31 |
| 11 | 19, 121, 455, 143, 31 |
| 13 | 19, 11, 455, 13, 31 |
| 19, 11, 35, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 13 x 19 x 11 x 35 x 1 x 31 = 778257480
Therefore, the lowest common multiple of 456,968,455,858,248 is 778257480.
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.
456 x 968 x 455 x 858 x 248 = 42735674741760
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
455 : 1, 5, 7, 13, 35, 65, 91, 455
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,968,455,858,248, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
968:2x 2x 2x 11x 11
455:5x 7x 13
858:2x 3x 11x 13
248:2x 2x 2x 31
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 11x 13 = 54912
Therefore, the value for common factors is 54912.
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 = 42735674741760/(1x54912)
LCM = 42735674741760/54912
LCM = 778257480
Thus, we can understand that the LCM of 456,968,455,858,248 is 778257480.
