Find LCM of 248,643,651,776,776 with Prime Factorization
| 2 | 248, 643, 651, 776, 776 |
| 2 | 124, 643, 651, 388, 388 |
| 2 | 62, 643, 651, 194, 194 |
| 31 | 31, 643, 651, 97, 97 |
| 97 | 1, 643, 21, 97, 97 |
| 1, 643, 21, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 31 x 97 x 1 x 643 x 21 x 1 x 1 = 324828168
Therefore, the lowest common multiple of 248,643,651,776,776 is 324828168.
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.
248 x 643 x 651 x 776 x 776 = 62512531275264
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
643 : 1, 643
651 : 1, 3, 7, 21, 31, 93, 217, 651
776 : 1, 2, 4, 8, 97, 194, 388, 776
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,643,651,776,776, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
643:643
651:3x 7x 31
776:2x 2x 2x 97
776:2x 2x 2x 97
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 31x 97 = 192448
Therefore, the value for common factors is 192448.
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 = 62512531275264/(1x192448)
LCM = 62512531275264/192448
LCM = 324828168
Thus, we can understand that the LCM of 248,643,651,776,776 is 324828168.
