Given numbers are 961,355,978,447,884
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,355,978,447,884 is 21973494698220.
Find LCM of 961,355,978,447,884 with Prime Factorization
| 2 | 961, 355, 978, 447, 884 |
| 3 | 961, 355, 489, 447, 442 |
| 961, 355, 163, 149, 442 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 961 x 355 x 163 x 149 x 442 = 21973494698220
Therefore, the lowest common multiple of 961,355,978,447,884 is 21973494698220.
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.
961 x 355 x 978 x 447 x 884 = 131840968189320
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.
961 : 1, 31, 961
355 : 1, 5, 71, 355
978 : 1, 2, 3, 6, 163, 326, 489, 978
447 : 1, 3, 149, 447
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,355,978,447,884, is 1.
Now, the common factors can be found like this.
961:31x 31
355:5x 71
978:2x 3x 163
447:3x 149
884:2x 2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 131840968189320/(1x6)
LCM = 131840968189320/6
LCM = 21973494698220
Thus, we can understand that the LCM of 961,355,978,447,884 is 21973494698220.
