Given numbers are 743,989,239,989,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,989,239,989,786 is 138040191258.
Find LCM of 743,989,239,989,786 with Prime Factorization
| 23 | 743, 989, 239, 989, 786 |
| 43 | 743, 43, 239, 43, 786 |
| 743, 1, 239, 1, 786 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 743 x 1 x 239 x 1 x 786 = 138040191258
Therefore, the lowest common multiple of 743,989,239,989,786 is 138040191258.
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.
743 x 989 x 239 x 989 x 786 = 136521749154162
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.
743 : 1, 743
989 : 1, 23, 43, 989
239 : 1, 239
989 : 1, 23, 43, 989
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,989,239,989,786, is 1.
Now, the common factors can be found like this.
743:743
989:23x 43
239:239
989:23x 43
786:2x 3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 43 = 989
Therefore, the value for common factors is 989.
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 = 136521749154162/(1x989)
LCM = 136521749154162/989
LCM = 138040191258
Thus, we can understand that the LCM of 743,989,239,989,786 is 138040191258.
