Given numbers are 987,436,851,581,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,436,851,581,218 is 30395640156.
Find LCM of 987,436,851,581,218 with Prime Factorization
2 | 987, 436, 851, 581, 218 |
7 | 987, 218, 851, 581, 109 |
109 | 141, 218, 851, 83, 109 |
141, 2, 851, 83, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 109 x 141 x 2 x 851 x 83 x 1 = 30395640156
Therefore, the lowest common multiple of 987,436,851,581,218 is 30395640156.
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 851 x 581 x 218 = 46383746878056
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
851 : 1, 23, 37, 851
581 : 1, 7, 83, 581
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,436,851,581,218, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
436:2x 2x 109
851:23x 37
581:7x 83
218:2x 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 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 = 46383746878056/(1x1526)
LCM = 46383746878056/1526
LCM = 30395640156
Thus, we can understand that the LCM of 987,436,851,581,218 is 30395640156.
