Find LCM of 361,702,252,891 with Prime Factorization
2 | 361, 702, 252, 891 |
3 | 361, 351, 126, 891 |
3 | 361, 117, 42, 297 |
3 | 361, 39, 14, 99 |
361, 13, 14, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 361 x 13 x 14 x 33 = 117080964
Therefore, the lowest common multiple of 361,702,252,891 is 117080964.
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.
361 x 702 x 252 x 891 = 56901348504
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.
361 : 1, 19, 361
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,702,252,891, is 1.
Now, the common factors can be found like this.
361:19x 19
702:2x 3x 3x 3x 13
252:2x 2x 3x 3x 7
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 56901348504/(1x486)
LCM = 56901348504/486
LCM = 117080964
Thus, we can understand that the LCM of 361,702,252,891 is 117080964.
