Given numbers are 649,618,729,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,618,729,354 is 97462926.
Find LCM of 649,618,729,354 with Prime Factorization
| 2 | 649, 618, 729, 354 |
| 3 | 649, 309, 729, 177 |
| 59 | 649, 103, 243, 59 |
| 11, 103, 243, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 59 x 11 x 103 x 243 x 1 = 97462926
Therefore, the lowest common multiple of 649,618,729,354 is 97462926.
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.
649 x 618 x 729 x 354 = 103505627412
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.
649 : 1, 11, 59, 649
618 : 1, 2, 3, 6, 103, 206, 309, 618
729 : 1, 3, 9, 27, 81, 243, 729
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,618,729,354, is 1.
Now, the common factors can be found like this.
649:11x 59
618:2x 3x 103
729:3x 3x 3x 3x 3x 3
354:2x 3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 59 = 1062
Therefore, the value for common factors is 1062.
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 = 103505627412/(1x1062)
LCM = 103505627412/1062
LCM = 97462926
Thus, we can understand that the LCM of 649,618,729,354 is 97462926.
