Given numbers are 372,540,690,547
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 372,540,690,547 is 210605940.
Find LCM of 372,540,690,547 with Prime Factorization
| 2 | 372, 540, 690, 547 |
| 2 | 186, 270, 345, 547 |
| 3 | 93, 135, 345, 547 |
| 5 | 31, 45, 115, 547 |
| 31, 9, 23, 547 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 31 x 9 x 23 x 547 = 210605940
Therefore, the lowest common multiple of 372,540,690,547 is 210605940.
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.
372 x 540 x 690 x 547 = 75818138400
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
547 : 1, 547
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,540,690,547, is 1.
Now, the common factors can be found like this.
372:2x 2x 3x 31
540:2x 2x 3x 3x 3x 5
690:2x 3x 5x 23
547:547
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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 75818138400/(1x360)
LCM = 75818138400/360
LCM = 210605940
Thus, we can understand that the LCM of 372,540,690,547 is 210605940.
