Given numbers are 678,757,989,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,757,989,309 is 52282830282.
Find LCM of 678,757,989,309 with Prime Factorization
| 3 | 678, 757, 989, 309 |
| 226, 757, 989, 103 |
Multiply the prime numbers at the bottom and the left side.
3 x 226 x 757 x 989 x 103 = 52282830282
Therefore, the lowest common multiple of 678,757,989,309 is 52282830282.
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.
678 x 757 x 989 x 309 = 156848490846
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
757 : 1, 757
989 : 1, 23, 43, 989
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,757,989,309, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
757:757
989:23x 43
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 156848490846/(1x3)
LCM = 156848490846/3
LCM = 52282830282
Thus, we can understand that the LCM of 678,757,989,309 is 52282830282.
