Given numbers are 868,406,607,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 868,406,607,922 is 7043805244.
Find LCM of 868,406,607,922 with Prime Factorization
| 2 | 868, 406, 607, 922 |
| 7 | 434, 203, 607, 461 |
| 62, 29, 607, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 62 x 29 x 607 x 461 = 7043805244
Therefore, the lowest common multiple of 868,406,607,922 is 7043805244.
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.
868 x 406 x 607 x 922 = 197226546832
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
406 : 1, 2, 7, 14, 29, 58, 203, 406
607 : 1, 607
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,406,607,922, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
406:2x 7x 29
607:607
922:2x 461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 197226546832/(1x28)
LCM = 197226546832/28
LCM = 7043805244
Thus, we can understand that the LCM of 868,406,607,922 is 7043805244.
