Given numbers are 103,272,440,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,272,440,242 is 16949680.
Find LCM of 103,272,440,242 with Prime Factorization
| 2 | 103, 272, 440, 242 |
| 2 | 103, 136, 220, 121 |
| 2 | 103, 68, 110, 121 |
| 11 | 103, 34, 55, 121 |
| 103, 34, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 103 x 34 x 5 x 11 = 16949680
Therefore, the lowest common multiple of 103,272,440,242 is 16949680.
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.
103 x 272 x 440 x 242 = 2983143680
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.
103 : 1, 103
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,272,440,242, is 1.
Now, the common factors can be found like this.
103:103
272:2x 2x 2x 2x 17
440:2x 2x 2x 5x 11
242:2x 11x 11
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 = 2983143680/(1x176)
LCM = 2983143680/176
LCM = 16949680
Thus, we can understand that the LCM of 103,272,440,242 is 16949680.
