Given numbers are 417,973,776,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,973,776,390 is 147234360.
Find LCM of 417,973,776,390 with Prime Factorization
2 | 417, 973, 776, 390 |
3 | 417, 973, 388, 195 |
139 | 139, 973, 388, 65 |
1, 7, 388, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 139 x 1 x 7 x 388 x 65 = 147234360
Therefore, the lowest common multiple of 417,973,776,390 is 147234360.
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.
417 x 973 x 776 x 390 = 122793456240
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.
417 : 1, 3, 139, 417
973 : 1, 7, 139, 973
776 : 1, 2, 4, 8, 97, 194, 388, 776
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 417,973,776,390, is 1.
Now, the common factors can be found like this.
417:3x 139
973:7x 139
776:2x 2x 2x 97
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 139 = 834
Therefore, the value for common factors is 834.
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 = 122793456240/(1x834)
LCM = 122793456240/834
LCM = 147234360
Thus, we can understand that the LCM of 417,973,776,390 is 147234360.
