Given numbers are 276,989,938,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 276,989,938,154 is 61227012.
Find LCM of 276,989,938,154 with Prime Factorization
2 | 276, 989, 938, 154 |
7 | 138, 989, 469, 77 |
23 | 138, 989, 67, 11 |
6, 43, 67, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 6 x 43 x 67 x 11 = 61227012
Therefore, the lowest common multiple of 276,989,938,154 is 61227012.
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.
276 x 989 x 938 x 154 = 39430195728
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.
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
989 : 1, 23, 43, 989
938 : 1, 2, 7, 14, 67, 134, 469, 938
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 276,989,938,154, is 1.
Now, the common factors can be found like this.
276:2x 2x 3x 23
989:23x 43
938:2x 7x 67
154:2x 7x 11
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 7x 23 = 644
Therefore, the value for common factors is 644.
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 = 39430195728/(1x644)
LCM = 39430195728/644
LCM = 61227012
Thus, we can understand that the LCM of 276,989,938,154 is 61227012.
