Given numbers are 478,231,455,679
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,231,455,679 is 696185490.
Find LCM of 478,231,455,679 with Prime Factorization
| 7 | 478, 231, 455, 679 |
| 478, 33, 65, 97 |
Multiply the prime numbers at the bottom and the left side.
7 x 478 x 33 x 65 x 97 = 696185490
Therefore, the lowest common multiple of 478,231,455,679 is 696185490.
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.
478 x 231 x 455 x 679 = 34113089010
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.
478 : 1, 2, 239, 478
231 : 1, 3, 7, 11, 21, 33, 77, 231
455 : 1, 5, 7, 13, 35, 65, 91, 455
679 : 1, 7, 97, 679
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,231,455,679, is 1.
Now, the common factors can be found like this.
478:2x 239
231:3x 7x 11
455:5x 7x 13
679:7x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 34113089010/(1x49)
LCM = 34113089010/49
LCM = 696185490
Thus, we can understand that the LCM of 478,231,455,679 is 696185490.
