Given numbers are 701,876,981,781,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 701,876,981,781,721 is 113072286764052.
Find LCM of 701,876,981,781,721 with Prime Factorization
| 3 | 701, 876, 981, 781, 721 |
| 701, 292, 327, 781, 721 |
Multiply the prime numbers at the bottom and the left side.
3 x 701 x 292 x 327 x 781 x 721 = 113072286764052
Therefore, the lowest common multiple of 701,876,981,781,721 is 113072286764052.
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.
701 x 876 x 981 x 781 x 721 = 339216860292156
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.
701 : 1, 701
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
981 : 1, 3, 9, 109, 327, 981
781 : 1, 11, 71, 781
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,876,981,781,721, is 1.
Now, the common factors can be found like this.
701:701
876:2x 2x 3x 73
981:3x 3x 109
781:11x 71
721:7x 103
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 = 339216860292156/(1x3)
LCM = 339216860292156/3
LCM = 113072286764052
Thus, we can understand that the LCM of 701,876,981,781,721 is 113072286764052.
