Given numbers are 831,989,817,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,989,817,774 is 93691926.
Find LCM of 831,989,817,774 with Prime Factorization
3 | 831, 989, 817, 774 |
43 | 277, 989, 817, 258 |
277, 23, 19, 6 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 277 x 23 x 19 x 6 = 93691926
Therefore, the lowest common multiple of 831,989,817,774 is 93691926.
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.
831 x 989 x 817 x 774 = 519709113522
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.
831 : 1, 3, 277, 831
989 : 1, 23, 43, 989
817 : 1, 19, 43, 817
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,989,817,774, is 1.
Now, the common factors can be found like this.
831:3x 277
989:23x 43
817:19x 43
774:2x 3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43x 43 = 5547
Therefore, the value for common factors is 5547.
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 = 519709113522/(1x5547)
LCM = 519709113522/5547
LCM = 93691926
Thus, we can understand that the LCM of 831,989,817,774 is 93691926.
