Find LCM of 612,391,544,628,664 with Prime Factorization
| 2 | 612, 391, 544, 628, 664 |
| 2 | 306, 391, 272, 314, 332 |
| 2 | 153, 391, 136, 157, 166 |
| 17 | 153, 391, 68, 157, 83 |
| 9, 23, 4, 157, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 9 x 23 x 4 x 157 x 83 = 1467394848
Therefore, the lowest common multiple of 612,391,544,628,664 is 1467394848.
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.
612 x 391 x 544 x 628 x 664 = 54281870217216
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
391 : 1, 17, 23, 391
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
628 : 1, 2, 4, 157, 314, 628
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,391,544,628,664, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
391:17x 23
544:2x 2x 2x 2x 2x 17
628:2x 2x 157
664:2x 2x 2x 83
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 2x 2x 2x 17x 17 = 36992
Therefore, the value for common factors is 36992.
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 = 54281870217216/(1x36992)
LCM = 54281870217216/36992
LCM = 1467394848
Thus, we can understand that the LCM of 612,391,544,628,664 is 1467394848.
