Given numbers are 741,681,546,873
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,681,546,873 is 685275318.
Find LCM of 741,681,546,873 with Prime Factorization
| 3 | 741, 681, 546, 873 |
| 13 | 247, 227, 182, 291 |
| 19, 227, 14, 291 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 19 x 227 x 14 x 291 = 685275318
Therefore, the lowest common multiple of 741,681,546,873 is 685275318.
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.
741 x 681 x 546 x 873 = 240531636618
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
681 : 1, 3, 227, 681
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
873 : 1, 3, 9, 97, 291, 873
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,681,546,873, is 3.
Now, the common factors can be found like this.
741:3x 13x 19
681:3x 227
546:2x 3x 7x 13
873:3x 3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 240531636618/(3x117)
LCM = 240531636618/351
LCM = 685275318
Thus, we can understand that the LCM of 741,681,546,873 is 685275318.
