The LCM of 532,286,788,798 is 44960916.
Find LCM of 532,286,788,798 with Prime Factorization
| 2 | 532, 286, 788, 798 |
| 2 | 266, 143, 394, 399 |
| 7 | 133, 143, 197, 399 |
| 19 | 19, 143, 197, 57 |
| 1, 143, 197, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 1 x 143 x 197 x 3 = 44960916
Therefore, the lowest common multiple of 532,286,788,798 is 44960916.
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.
532 x 286 x 788 x 798 = 95676829248
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.
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
286 : 1, 2, 11, 13, 22, 26, 143, 286
788 : 1, 2, 4, 197, 394, 788
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 532,286,788,798, is 2.
Now, the common factors can be found like this.
532:2x 2x 7x 19
286:2x 11x 13
788:2x 2x 197
798:2x 3x 7x 19
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 7x 19 = 1064
Therefore, the value for common factors is 1064.
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 = 95676829248/(2x1064)
LCM = 95676829248/2128
LCM = 44960916
Thus, we can understand that the LCM of 532,286,788,798 is 44960916.
