Given numbers are 699,438,169,908,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,438,169,908,858 is 86132147244.
Find LCM of 699,438,169,908,858 with Prime Factorization
| 2 | 699, 438, 169, 908, 858 |
| 3 | 699, 219, 169, 454, 429 |
| 13 | 233, 73, 169, 454, 143 |
| 233, 73, 13, 454, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 233 x 73 x 13 x 454 x 11 = 86132147244
Therefore, the lowest common multiple of 699,438,169,908,858 is 86132147244.
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.
699 x 438 x 169 x 908 x 858 = 40309844910192
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.
699 : 1, 3, 233, 699
438 : 1, 2, 3, 6, 73, 146, 219, 438
169 : 1, 13, 169
908 : 1, 2, 4, 227, 454, 908
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,438,169,908,858, is 1.
Now, the common factors can be found like this.
699:3x 233
438:2x 3x 73
169:13x 13
908:2x 2x 227
858:2x 3x 11x 13
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 3x 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 40309844910192/(1x468)
LCM = 40309844910192/468
LCM = 86132147244
Thus, we can understand that the LCM of 699,438,169,908,858 is 86132147244.
