Given numbers are 854,991,861,150,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 854,991,861,150,342 is 148337686350.
Find LCM of 854,991,861,150,342 with Prime Factorization
| 2 | 854, 991, 861, 150, 342 |
| 3 | 427, 991, 861, 75, 171 |
| 7 | 427, 991, 287, 25, 57 |
| 61, 991, 41, 25, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 61 x 991 x 41 x 25 x 57 = 148337686350
Therefore, the lowest common multiple of 854,991,861,150,342 is 148337686350.
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.
854 x 991 x 861 x 150 x 342 = 37381096960200
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.
854 : 1, 2, 7, 14, 61, 122, 427, 854
991 : 1, 991
861 : 1, 3, 7, 21, 41, 123, 287, 861
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,991,861,150,342, is 1.
Now, the common factors can be found like this.
854:2x 7x 61
991:991
861:3x 7x 41
150:2x 3x 5x 5
342:2x 3x 3x 19
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 37381096960200/(1x252)
LCM = 37381096960200/252
LCM = 148337686350
Thus, we can understand that the LCM of 854,991,861,150,342 is 148337686350.
