Given numbers are 136,247,247,762,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 136,247,247,762,221 is 12798552.
Find LCM of 136,247,247,762,221 with Prime Factorization
| 2 | 136, 247, 247, 762, 221 |
| 13 | 68, 247, 247, 381, 221 |
| 17 | 68, 19, 19, 381, 17 |
| 19 | 4, 19, 19, 381, 1 |
| 4, 1, 1, 381, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 19 x 4 x 1 x 1 x 381 x 1 = 12798552
Therefore, the lowest common multiple of 136,247,247,762,221 is 12798552.
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.
136 x 247 x 247 x 762 x 221 = 1397269116048
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.
136 : 1, 2, 4, 8, 17, 34, 68, 136
247 : 1, 13, 19, 247
247 : 1, 13, 19, 247
762 : 1, 2, 3, 6, 127, 254, 381, 762
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,247,247,762,221, is 1.
Now, the common factors can be found like this.
136:2x 2x 2x 17
247:13x 19
247:13x 19
762:2x 3x 127
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13x 17x 19 = 109174
Therefore, the value for common factors is 109174.
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 = 1397269116048/(1x109174)
LCM = 1397269116048/109174
LCM = 12798552
Thus, we can understand that the LCM of 136,247,247,762,221 is 12798552.
