Given numbers are 802,764,388,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,764,388,621 is 18454448268.
Find LCM of 802,764,388,621 with Prime Factorization
| 2 | 802, 764, 388, 621 |
| 2 | 401, 382, 194, 621 |
| 401, 191, 97, 621 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 401 x 191 x 97 x 621 = 18454448268
Therefore, the lowest common multiple of 802,764,388,621 is 18454448268.
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.
802 x 764 x 388 x 621 = 147635586144
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.
802 : 1, 2, 401, 802
764 : 1, 2, 4, 191, 382, 764
388 : 1, 2, 4, 97, 194, 388
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,764,388,621, is 1.
Now, the common factors can be found like this.
802:2x 401
764:2x 2x 191
388:2x 2x 97
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 147635586144/(1x8)
LCM = 147635586144/8
LCM = 18454448268
Thus, we can understand that the LCM of 802,764,388,621 is 18454448268.
