Given numbers are 7,642,241,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,642,241,681 is 245853258.
Find LCM of 7,642,241,681 with Prime Factorization
3 | 7, 642, 241, 681 |
7, 214, 241, 227 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 214 x 241 x 227 = 245853258
Therefore, the lowest common multiple of 7,642,241,681 is 245853258.
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.
7 x 642 x 241 x 681 = 737559774
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.
7 : 1, 7
642 : 1, 2, 3, 6, 107, 214, 321, 642
241 : 1, 241
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,642,241,681, is 1.
Now, the common factors can be found like this.
7:7
642:2x 3x 107
241:241
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 737559774/(1x3)
LCM = 737559774/3
LCM = 245853258
Thus, we can understand that the LCM of 7,642,241,681 is 245853258.
