Given numbers are 698,618,324,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,618,324,744 is 722103336.
Find LCM of 698,618,324,744 with Prime Factorization
| 2 | 698, 618, 324, 744 |
| 2 | 349, 309, 162, 372 |
| 3 | 349, 309, 81, 186 |
| 349, 103, 27, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 349 x 103 x 27 x 62 = 722103336
Therefore, the lowest common multiple of 698,618,324,744 is 722103336.
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.
698 x 618 x 324 x 744 = 103982880384
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.
698 : 1, 2, 349, 698
618 : 1, 2, 3, 6, 103, 206, 309, 618
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,618,324,744, is 2.
Now, the common factors can be found like this.
698:2x 349
618:2x 3x 103
324:2x 2x 3x 3x 3x 3
744:2x 2x 2x 3x 31
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 103982880384/(2x72)
LCM = 103982880384/144
LCM = 722103336
Thus, we can understand that the LCM of 698,618,324,744 is 722103336.
