Given numbers are 421,481,664,298,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,481,664,298,546 is 420727417656.
Find LCM of 421,481,664,298,546 with Prime Factorization
2 | 421, 481, 664, 298, 546 |
13 | 421, 481, 332, 149, 273 |
421, 37, 332, 149, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 421 x 37 x 332 x 149 x 21 = 420727417656
Therefore, the lowest common multiple of 421,481,664,298,546 is 420727417656.
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.
421 x 481 x 664 x 298 x 546 = 21877825718112
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.
421 : 1, 421
481 : 1, 13, 37, 481
664 : 1, 2, 4, 8, 83, 166, 332, 664
298 : 1, 2, 149, 298
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,481,664,298,546, is 1.
Now, the common factors can be found like this.
421:421
481:13x 37
664:2x 2x 2x 83
298:2x 149
546:2x 3x 7x 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 2x 13 = 52
Therefore, the value for common factors is 52.
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 = 21877825718112/(1x52)
LCM = 21877825718112/52
LCM = 420727417656
Thus, we can understand that the LCM of 421,481,664,298,546 is 420727417656.
