Given numbers are 610,791,565,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 610,791,565,686 is 23642990.
Find LCM of 610,791,565,686 with Prime Factorization
| 2 | 610, 791, 565, 686 |
| 5 | 305, 791, 565, 343 |
| 7 | 61, 791, 113, 343 |
| 113 | 61, 113, 113, 49 |
| 61, 1, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 113 x 61 x 1 x 1 x 49 = 23642990
Therefore, the lowest common multiple of 610,791,565,686 is 23642990.
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.
610 x 791 x 565 x 686 = 187016050900
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.
610 : 1, 2, 5, 10, 61, 122, 305, 610
791 : 1, 7, 113, 791
565 : 1, 5, 113, 565
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 610,791,565,686, is 1.
Now, the common factors can be found like this.
610:2x 5x 61
791:7x 113
565:5x 113
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 113 = 7910
Therefore, the value for common factors is 7910.
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 = 187016050900/(1x7910)
LCM = 187016050900/7910
LCM = 23642990
Thus, we can understand that the LCM of 610,791,565,686 is 23642990.
