Given numbers are 7860,7729
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7860,7729 is 463740.
Find LCM of 7860,7729 with Prime Factorization
| 131 | 7860, 7729 |
| 60, 59 |
Multiply the prime numbers at the bottom and the left side.
131 x 60 x 59 = 463740
Therefore, the lowest common multiple of 7860,7729 is 463740.
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.
7860 x 7729 = 60749940
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.
7860 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60, 131, 262, 393, 524, 655, 786, 1310, 1572, 1965, 2620, 3930, 7860
7729 : 1, 59, 131, 7729
131 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7860,7729, is 131.
Now, the common factors can be found like this.
7860:2x 2x 3x 5x 131
7729:59x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 60749940/(131x1)
LCM = 60749940/131
LCM = 463740
Thus, we can understand that the LCM of 7860,7729 is 463740.
