Given numbers are 428,118,881,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,118,881,661 is 14705274932.
Find LCM of 428,118,881,661 with Prime Factorization
| 2 | 428, 118, 881, 661 |
| 214, 59, 881, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 214 x 59 x 881 x 661 = 14705274932
Therefore, the lowest common multiple of 428,118,881,661 is 14705274932.
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.
428 x 118 x 881 x 661 = 29410549864
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.
428 : 1, 2, 4, 107, 214, 428
118 : 1, 2, 59, 118
881 : 1, 881
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,118,881,661, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
118:2x 59
881:881
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 29410549864/(1x2)
LCM = 29410549864/2
LCM = 14705274932
Thus, we can understand that the LCM of 428,118,881,661 is 14705274932.
