Given numbers are 702,905,705,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 702,905,705,611 is 29859570.
Find LCM of 702,905,705,611 with Prime Factorization
| 3 | 702, 905, 705, 611 |
| 5 | 234, 905, 235, 611 |
| 13 | 234, 181, 47, 611 |
| 47 | 18, 181, 47, 47 |
| 18, 181, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 47 x 18 x 181 x 1 x 1 = 29859570
Therefore, the lowest common multiple of 702,905,705,611 is 29859570.
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.
702 x 905 x 705 x 611 = 273662959050
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.
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
905 : 1, 5, 181, 905
705 : 1, 3, 5, 15, 47, 141, 235, 705
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,905,705,611, is 1.
Now, the common factors can be found like this.
702:2x 3x 3x 3x 13
905:5x 181
705:3x 5x 47
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13x 47 = 9165
Therefore, the value for common factors is 9165.
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 = 273662959050/(1x9165)
LCM = 273662959050/9165
LCM = 29859570
Thus, we can understand that the LCM of 702,905,705,611 is 29859570.
