Given numbers are 713,561,840,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 713,561,840,161 is 111998040.
Find LCM of 713,561,840,161 with Prime Factorization
| 3 | 713, 561, 840, 161 |
| 7 | 713, 187, 280, 161 |
| 23 | 713, 187, 40, 23 |
| 31, 187, 40, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 23 x 31 x 187 x 40 x 1 = 111998040
Therefore, the lowest common multiple of 713,561,840,161 is 111998040.
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.
713 x 561 x 840 x 161 = 54095053320
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.
713 : 1, 23, 31, 713
561 : 1, 3, 11, 17, 33, 51, 187, 561
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,561,840,161, is 1.
Now, the common factors can be found like this.
713:23x 31
561:3x 11x 17
840:2x 2x 2x 3x 5x 7
161:7x 23
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 23 = 483
Therefore, the value for common factors is 483.
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 = 54095053320/(1x483)
LCM = 54095053320/483
LCM = 111998040
Thus, we can understand that the LCM of 713,561,840,161 is 111998040.
