Given numbers are 791,246,805,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,246,805,861 is 22377390.
Find LCM of 791,246,805,861 with Prime Factorization
| 3 | 791, 246, 805, 861 |
| 7 | 791, 82, 805, 287 |
| 41 | 113, 82, 115, 41 |
| 113, 2, 115, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 41 x 113 x 2 x 115 x 1 = 22377390
Therefore, the lowest common multiple of 791,246,805,861 is 22377390.
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.
791 x 246 x 805 x 861 = 134868529530
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.
791 : 1, 7, 113, 791
246 : 1, 2, 3, 6, 41, 82, 123, 246
805 : 1, 5, 7, 23, 35, 115, 161, 805
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,246,805,861, is 1.
Now, the common factors can be found like this.
791:7x 113
246:2x 3x 41
805:5x 7x 23
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 41 = 6027
Therefore, the value for common factors is 6027.
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 = 134868529530/(1x6027)
LCM = 134868529530/6027
LCM = 22377390
Thus, we can understand that the LCM of 791,246,805,861 is 22377390.
