The LCM of 711,621,465,912,855 is 2311660080.
Find LCM of 711,621,465,912,855 with Prime Factorization
| 3 | 711, 621, 465, 912, 855 |
| 3 | 237, 207, 155, 304, 285 |
| 5 | 79, 69, 155, 304, 95 |
| 19 | 79, 69, 31, 304, 19 |
| 79, 69, 31, 16, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 79 x 69 x 31 x 16 x 1 = 2311660080
Therefore, the lowest common multiple of 711,621,465,912,855 is 2311660080.
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.
711 x 621 x 465 x 912 x 855 = 160094018840400
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.
711 : 1, 3, 9, 79, 237, 711
621 : 1, 3, 9, 23, 27, 69, 207, 621
465 : 1, 3, 5, 15, 31, 93, 155, 465
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,621,465,912,855, is 3.
Now, the common factors can be found like this.
711:3x 3x 79
621:3x 3x 3x 23
465:3x 5x 31
912:2x 2x 2x 2x 3x 19
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 5x 19 = 23085
Therefore, the value for common factors is 23085.
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 = 160094018840400/(3x23085)
LCM = 160094018840400/69255
LCM = 2311660080
Thus, we can understand that the LCM of 711,621,465,912,855 is 2311660080.
