Given numbers are 989,151,276,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,151,276,261 is 155909916.
Find LCM of 989,151,276,261 with Prime Factorization
3 | 989, 151, 276, 261 |
23 | 989, 151, 92, 87 |
43, 151, 4, 87 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 43 x 151 x 4 x 87 = 155909916
Therefore, the lowest common multiple of 989,151,276,261 is 155909916.
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.
989 x 151 x 276 x 261 = 10757784204
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.
989 : 1, 23, 43, 989
151 : 1, 151
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,151,276,261, is 1.
Now, the common factors can be found like this.
989:23x 43
151:151
276:2x 2x 3x 23
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23 = 69
Therefore, the value for common factors is 69.
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 = 10757784204/(1x69)
LCM = 10757784204/69
LCM = 155909916
Thus, we can understand that the LCM of 989,151,276,261 is 155909916.
