Given numbers are 717,740,394,855,763
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,740,394,855,763 is 4545864591660.
Find LCM of 717,740,394,855,763 with Prime Factorization
| 2 | 717, 740, 394, 855, 763 |
| 3 | 717, 370, 197, 855, 763 |
| 5 | 239, 370, 197, 285, 763 |
| 239, 74, 197, 57, 763 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 239 x 74 x 197 x 57 x 763 = 4545864591660
Therefore, the lowest common multiple of 717,740,394,855,763 is 4545864591660.
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.
717 x 740 x 394 x 855 x 763 = 136375937749800
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.
717 : 1, 3, 239, 717
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
394 : 1, 2, 197, 394
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,740,394,855,763, is 1.
Now, the common factors can be found like this.
717:3x 239
740:2x 2x 5x 37
394:2x 197
855:3x 3x 5x 19
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 136375937749800/(1x30)
LCM = 136375937749800/30
LCM = 4545864591660
Thus, we can understand that the LCM of 717,740,394,855,763 is 4545864591660.
