Given numbers are 962,638,440,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 962,638,440,391 is 2399785960.
Find LCM of 962,638,440,391 with Prime Factorization
| 2 | 962, 638, 440, 391 |
| 11 | 481, 319, 220, 391 |
| 481, 29, 20, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 481 x 29 x 20 x 391 = 2399785960
Therefore, the lowest common multiple of 962,638,440,391 is 2399785960.
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.
962 x 638 x 440 x 391 = 105590582240
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.
962 : 1, 2, 13, 26, 37, 74, 481, 962
638 : 1, 2, 11, 22, 29, 58, 319, 638
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 962,638,440,391, is 1.
Now, the common factors can be found like this.
962:2x 13x 37
638:2x 11x 29
440:2x 2x 2x 5x 11
391:17x 23
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 11 = 44
Therefore, the value for common factors is 44.
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 = 105590582240/(1x44)
LCM = 105590582240/44
LCM = 2399785960
Thus, we can understand that the LCM of 962,638,440,391 is 2399785960.
