Given numbers are 489,688,985,962,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,688,985,962,172 is 159396435120.
Find LCM of 489,688,985,962,172 with Prime Factorization
| 2 | 489, 688, 985, 962, 172 |
| 2 | 489, 344, 985, 481, 86 |
| 43 | 489, 172, 985, 481, 43 |
| 489, 4, 985, 481, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 489 x 4 x 985 x 481 x 1 = 159396435120
Therefore, the lowest common multiple of 489,688,985,962,172 is 159396435120.
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.
489 x 688 x 985 x 962 x 172 = 54832373681280
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.
489 : 1, 3, 163, 489
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
985 : 1, 5, 197, 985
962 : 1, 2, 13, 26, 37, 74, 481, 962
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,688,985,962,172, is 1.
Now, the common factors can be found like this.
489:3x 163
688:2x 2x 2x 2x 43
985:5x 197
962:2x 13x 37
172:2x 2x 43
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 43 = 344
Therefore, the value for common factors is 344.
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 = 54832373681280/(1x344)
LCM = 54832373681280/344
LCM = 159396435120
Thus, we can understand that the LCM of 489,688,985,962,172 is 159396435120.
