Given numbers are 722,981,622,403,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,981,622,403,742 is 32934081033126.
Find LCM of 722,981,622,403,742 with Prime Factorization
| 2 | 722, 981, 622, 403, 742 |
| 361, 981, 311, 403, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 361 x 981 x 311 x 403 x 371 = 32934081033126
Therefore, the lowest common multiple of 722,981,622,403,742 is 32934081033126.
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.
722 x 981 x 622 x 403 x 742 = 131736324132504
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.
722 : 1, 2, 19, 38, 361, 722
981 : 1, 3, 9, 109, 327, 981
622 : 1, 2, 311, 622
403 : 1, 13, 31, 403
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,981,622,403,742, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
981:3x 3x 109
622:2x 311
403:13x 31
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 131736324132504/(1x4)
LCM = 131736324132504/4
LCM = 32934081033126
Thus, we can understand that the LCM of 722,981,622,403,742 is 32934081033126.
