Given numbers are 987,436,763,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,436,763,146 is 31414236.
Find LCM of 987,436,763,146 with Prime Factorization
| 2 | 987, 436, 763, 146 |
| 7 | 987, 218, 763, 73 |
| 109 | 141, 218, 109, 73 |
| 141, 2, 1, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 109 x 141 x 2 x 1 x 73 = 31414236
Therefore, the lowest common multiple of 987,436,763,146 is 31414236.
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 436 x 763 x 146 = 47938124136
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
436 : 1, 2, 4, 109, 218, 436
763 : 1, 7, 109, 763
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,436,763,146, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
436:2x 2x 109
763:7x 109
146:2x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 109 = 1526
Therefore, the value for common factors is 1526.
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 = 47938124136/(1x1526)
LCM = 47938124136/1526
LCM = 31414236
Thus, we can understand that the LCM of 987,436,763,146 is 31414236.
