Given numbers are 821,979,374,868,701
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,979,374,868,701 is 8314047730604.
Find LCM of 821,979,374,868,701 with Prime Factorization
| 2 | 821, 979, 374, 868, 701 |
| 11 | 821, 979, 187, 434, 701 |
| 821, 89, 17, 434, 701 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 821 x 89 x 17 x 434 x 701 = 8314047730604
Therefore, the lowest common multiple of 821,979,374,868,701 is 8314047730604.
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.
821 x 979 x 374 x 868 x 701 = 182909050073288
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.
821 : 1, 821
979 : 1, 11, 89, 979
374 : 1, 2, 11, 17, 22, 34, 187, 374
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
701 : 1, 701
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,979,374,868,701, is 1.
Now, the common factors can be found like this.
821:821
979:11x 89
374:2x 11x 17
868:2x 2x 7x 31
701:701
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 182909050073288/(1x22)
LCM = 182909050073288/22
LCM = 8314047730604
Thus, we can understand that the LCM of 821,979,374,868,701 is 8314047730604.
