Given numbers are 987,481,959,402,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,481,959,402,168 is 34861621704.
Find LCM of 987,481,959,402,168 with Prime Factorization
| 2 | 987, 481, 959, 402, 168 |
| 3 | 987, 481, 959, 201, 84 |
| 7 | 329, 481, 959, 67, 28 |
| 47, 481, 137, 67, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 47 x 481 x 137 x 67 x 4 = 34861621704
Therefore, the lowest common multiple of 987,481,959,402,168 is 34861621704.
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 481 x 959 x 402 x 168 = 30747950342928
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
481 : 1, 13, 37, 481
959 : 1, 7, 137, 959
402 : 1, 2, 3, 6, 67, 134, 201, 402
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,481,959,402,168, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
481:13x 37
959:7x 137
402:2x 3x 67
168:2x 2x 2x 3x 7
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 7 = 882
Therefore, the value for common factors is 882.
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 = 30747950342928/(1x882)
LCM = 30747950342928/882
LCM = 34861621704
Thus, we can understand that the LCM of 987,481,959,402,168 is 34861621704.
