Find LCM of 702,489,188,858,987 with Prime Factorization
| 2 | 702, 489, 188, 858, 987 |
| 3 | 351, 489, 94, 429, 987 |
| 13 | 117, 163, 94, 143, 329 |
| 47 | 9, 163, 94, 11, 329 |
| 9, 163, 2, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 47 x 9 x 163 x 2 x 11 x 7 = 828215388
Therefore, the lowest common multiple of 702,489,188,858,987 is 828215388.
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.
702 x 489 x 188 x 858 x 987 = 54652277023344
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.
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
489 : 1, 3, 163, 489
188 : 1, 2, 4, 47, 94, 188
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,489,188,858,987, is 1.
Now, the common factors can be found like this.
702:2x 3x 3x 3x 13
489:3x 163
188:2x 2x 47
858:2x 3x 11x 13
987:3x 7x 47
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 3x 13x 47 = 65988
Therefore, the value for common factors is 65988.
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 = 54652277023344/(1x65988)
LCM = 54652277023344/65988
LCM = 828215388
Thus, we can understand that the LCM of 702,489,188,858,987 is 828215388.
