Given numbers are 965,490,939,649,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 965,490,939,649,242 is 633951980970.
Find LCM of 965,490,939,649,242 with Prime Factorization
| 2 | 965, 490, 939, 649, 242 |
| 5 | 965, 245, 939, 649, 121 |
| 11 | 193, 49, 939, 649, 121 |
| 193, 49, 939, 59, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 193 x 49 x 939 x 59 x 11 = 633951980970
Therefore, the lowest common multiple of 965,490,939,649,242 is 633951980970.
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.
965 x 490 x 939 x 649 x 242 = 69734717906700
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.
965 : 1, 5, 193, 965
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
939 : 1, 3, 313, 939
649 : 1, 11, 59, 649
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 965,490,939,649,242, is 1.
Now, the common factors can be found like this.
965:5x 193
490:2x 5x 7x 7
939:3x 313
649:11x 59
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 69734717906700/(1x110)
LCM = 69734717906700/110
LCM = 633951980970
Thus, we can understand that the LCM of 965,490,939,649,242 is 633951980970.
