Given numbers are 369,720,618,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 369,720,618,354 is 179393040.
Find LCM of 369,720,618,354 with Prime Factorization
| 2 | 369, 720, 618, 354 |
| 3 | 369, 360, 309, 177 |
| 3 | 123, 120, 103, 59 |
| 41, 40, 103, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 40 x 103 x 59 = 179393040
Therefore, the lowest common multiple of 369,720,618,354 is 179393040.
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.
369 x 720 x 618 x 354 = 58123344960
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.
369 : 1, 3, 9, 41, 123, 369
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
618 : 1, 2, 3, 6, 103, 206, 309, 618
354 : 1, 2, 3, 6, 59, 118, 177, 354
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,720,618,354, is 3.
Now, the common factors can be found like this.
369:3x 3x 41
720:2x 2x 2x 2x 3x 3x 5
618:2x 3x 103
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 2x 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 58123344960/(3x108)
LCM = 58123344960/324
LCM = 179393040
Thus, we can understand that the LCM of 369,720,618,354 is 179393040.
