Given numbers are 748,681,871,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,681,871,681 is 443676948.
Find LCM of 748,681,871,681 with Prime Factorization
| 3 | 748, 681, 871, 681 |
| 227 | 748, 227, 871, 227 |
| 748, 1, 871, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 227 x 748 x 1 x 871 x 1 = 443676948
Therefore, the lowest common multiple of 748,681,871,681 is 443676948.
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.
748 x 681 x 871 x 681 = 302144001588
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
681 : 1, 3, 227, 681
871 : 1, 13, 67, 871
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,681,871,681, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
681:3x 227
871:13x 67
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.
3x 227 = 681
Therefore, the value for common factors is 681.
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 = 302144001588/(1x681)
LCM = 302144001588/681
LCM = 443676948
Thus, we can understand that the LCM of 748,681,871,681 is 443676948.
