Given numbers are 642,732,976,241
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,732,976,241 is 75504336.
Find LCM of 642,732,976,241 with Prime Factorization
2 | 642, 732, 976, 241 |
2 | 321, 366, 488, 241 |
3 | 321, 183, 244, 241 |
61 | 107, 61, 244, 241 |
107, 1, 4, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 61 x 107 x 1 x 4 x 241 = 75504336
Therefore, the lowest common multiple of 642,732,976,241 is 75504336.
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.
642 x 732 x 976 x 241 = 110538347904
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
241 : 1, 241
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,732,976,241, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
732:2x 2x 3x 61
976:2x 2x 2x 2x 61
241:241
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 2x 3x 61 = 1464
Therefore, the value for common factors is 1464.
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 = 110538347904/(1x1464)
LCM = 110538347904/1464
LCM = 75504336
Thus, we can understand that the LCM of 642,732,976,241 is 75504336.
