Given numbers are 220,654,344,221,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,654,344,221,649 is 80670206760.
Find LCM of 220,654,344,221,649 with Prime Factorization
| 2 | 220, 654, 344, 221, 649 |
| 2 | 110, 327, 172, 221, 649 |
| 11 | 55, 327, 86, 221, 649 |
| 5, 327, 86, 221, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 5 x 327 x 86 x 221 x 59 = 80670206760
Therefore, the lowest common multiple of 220,654,344,221,649 is 80670206760.
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.
220 x 654 x 344 x 221 x 649 = 7098978194880
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
654 : 1, 2, 3, 6, 109, 218, 327, 654
344 : 1, 2, 4, 8, 43, 86, 172, 344
221 : 1, 13, 17, 221
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,654,344,221,649, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
654:2x 3x 109
344:2x 2x 2x 43
221:13x 17
649:11x 59
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 11 = 88
Therefore, the value for common factors is 88.
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 = 7098978194880/(1x88)
LCM = 7098978194880/88
LCM = 80670206760
Thus, we can understand that the LCM of 220,654,344,221,649 is 80670206760.
