Find LCM of 654,636,616,881,649 with Prime Factorization
| 2 | 654, 636, 616, 881, 649 |
| 2 | 327, 318, 308, 881, 649 |
| 3 | 327, 159, 154, 881, 649 |
| 11 | 109, 53, 154, 881, 649 |
| 109, 53, 14, 881, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 109 x 53 x 14 x 881 x 59 = 554922398184
Therefore, the lowest common multiple of 654,636,616,881,649 is 554922398184.
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.
654 x 636 x 616 x 881 x 649 = 146499513120576
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
881 : 1, 881
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,636,616,881,649, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
636:2x 2x 3x 53
616:2x 2x 2x 7x 11
881:881
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 146499513120576/(1x264)
LCM = 146499513120576/264
LCM = 554922398184
Thus, we can understand that the LCM of 654,636,616,881,649 is 554922398184.
