Given numbers are 248,242,671,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,242,671,856 is 195862216.
Find LCM of 248,242,671,856 with Prime Factorization
| 2 | 248, 242, 671, 856 |
| 2 | 124, 121, 671, 428 |
| 2 | 62, 121, 671, 214 |
| 11 | 31, 121, 671, 107 |
| 31, 11, 61, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 31 x 11 x 61 x 107 = 195862216
Therefore, the lowest common multiple of 248,242,671,856 is 195862216.
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 242 x 671 x 856 = 34471750016
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
242 : 1, 2, 11, 22, 121, 242
671 : 1, 11, 61, 671
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,242,671,856, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
242:2x 11x 11
671:11x 61
856:2x 2x 2x 107
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 11 = 176
Therefore, the value for common factors is 176.
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 = 34471750016/(1x176)
LCM = 34471750016/176
LCM = 195862216
Thus, we can understand that the LCM of 248,242,671,856 is 195862216.
