Given numbers are 888,681,781,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 888,681,781,407 is 157430856.
Find LCM of 888,681,781,407 with Prime Factorization
| 3 | 888, 681, 781, 407 |
| 11 | 296, 227, 781, 407 |
| 37 | 296, 227, 71, 37 |
| 8, 227, 71, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 37 x 8 x 227 x 71 x 1 = 157430856
Therefore, the lowest common multiple of 888,681,781,407 is 157430856.
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.
888 x 681 x 781 x 407 = 192223075176
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
681 : 1, 3, 227, 681
781 : 1, 11, 71, 781
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,681,781,407, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
681:3x 227
781:11x 71
407:11x 37
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 37 = 1221
Therefore, the value for common factors is 1221.
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 = 192223075176/(1x1221)
LCM = 192223075176/1221
LCM = 157430856
Thus, we can understand that the LCM of 888,681,781,407 is 157430856.
