Find LCM of 987,658,651,835,654 with Prime Factorization
| 2 | 987, 658, 651, 835, 654 |
| 3 | 987, 329, 651, 835, 327 |
| 7 | 329, 329, 217, 835, 109 |
| 47 | 47, 47, 31, 835, 109 |
| 1, 1, 31, 835, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 47 x 1 x 1 x 31 x 835 x 109 = 5569571910
Therefore, the lowest common multiple of 987,658,651,835,654 is 5569571910.
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.
987 x 658 x 651 x 835 x 654 = 230881033957140
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
658 : 1, 2, 7, 14, 47, 94, 329, 658
651 : 1, 3, 7, 21, 31, 93, 217, 651
835 : 1, 5, 167, 835
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,658,651,835,654, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
658:2x 7x 47
651:3x 7x 31
835:5x 167
654:2x 3x 109
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 7x 7x 47 = 41454
Therefore, the value for common factors is 41454.
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 = 230881033957140/(1x41454)
LCM = 230881033957140/41454
LCM = 5569571910
Thus, we can understand that the LCM of 987,658,651,835,654 is 5569571910.
