Given numbers are 807,802,699,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,802,699,390 is 9802056030.
Find LCM of 807,802,699,390 with Prime Factorization
| 2 | 807, 802, 699, 390 |
| 3 | 807, 401, 699, 195 |
| 269, 401, 233, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 269 x 401 x 233 x 65 = 9802056030
Therefore, the lowest common multiple of 807,802,699,390 is 9802056030.
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.
807 x 802 x 699 x 390 = 176437008540
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.
807 : 1, 3, 269, 807
802 : 1, 2, 401, 802
699 : 1, 3, 233, 699
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,802,699,390, is 1.
Now, the common factors can be found like this.
807:3x 269
802:2x 401
699:3x 233
390:2x 3x 5x 13
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 3 = 18
Therefore, the value for common factors is 18.
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 = 176437008540/(1x18)
LCM = 176437008540/18
LCM = 9802056030
Thus, we can understand that the LCM of 807,802,699,390 is 9802056030.
