Given numbers are 681,748,539,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,748,539,681 is 24960012.
Find LCM of 681,748,539,681 with Prime Factorization
| 3 | 681, 748, 539, 681 |
| 11 | 227, 748, 539, 227 |
| 227 | 227, 68, 49, 227 |
| 1, 68, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 227 x 1 x 68 x 49 x 1 = 24960012
Therefore, the lowest common multiple of 681,748,539,681 is 24960012.
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.
681 x 748 x 539 x 681 = 186975449892
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.
681 : 1, 3, 227, 681
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
539 : 1, 7, 11, 49, 77, 539
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,748,539,681, is 1.
Now, the common factors can be found like this.
681:3x 227
748:2x 2x 11x 17
539:7x 7x 11
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 11x 227 = 7491
Therefore, the value for common factors is 7491.
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 = 186975449892/(1x7491)
LCM = 186975449892/7491
LCM = 24960012
Thus, we can understand that the LCM of 681,748,539,681 is 24960012.
