The LCM of 649,649,171,221,477 is 1299897027.
Find LCM of 649,649,171,221,477 with Prime Factorization
| 3 | 649, 649, 171, 221, 477 |
| 3 | 649, 649, 57, 221, 159 |
| 11 | 649, 649, 19, 221, 53 |
| 59 | 59, 59, 19, 221, 53 |
| 1, 1, 19, 221, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 59 x 1 x 1 x 19 x 221 x 53 = 1299897027
Therefore, the lowest common multiple of 649,649,171,221,477 is 1299897027.
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.
649 x 649 x 171 x 221 x 477 = 7592698534707
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.
649 : 1, 11, 59, 649
649 : 1, 11, 59, 649
171 : 1, 3, 9, 19, 57, 171
221 : 1, 13, 17, 221
477 : 1, 3, 9, 53, 159, 477
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,649,171,221,477, is 1.
Now, the common factors can be found like this.
649:11x 59
649:11x 59
171:3x 3x 19
221:13x 17
477:3x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 59 = 5841
Therefore, the value for common factors is 5841.
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 = 7592698534707/(1x5841)
LCM = 7592698534707/5841
LCM = 1299897027
Thus, we can understand that the LCM of 649,649,171,221,477 is 1299897027.
