Given numbers are 747,441,803,664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,441,803,664 is 235137672.
Find LCM of 747,441,803,664 with Prime Factorization
| 3 | 747, 441, 803, 664 |
| 3 | 249, 147, 803, 664 |
| 83 | 83, 49, 803, 664 |
| 1, 49, 803, 8 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 83 x 1 x 49 x 803 x 8 = 235137672
Therefore, the lowest common multiple of 747,441,803,664 is 235137672.
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.
747 x 441 x 803 x 664 = 175647840984
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.
747 : 1, 3, 9, 83, 249, 747
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
803 : 1, 11, 73, 803
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,441,803,664, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
441:3x 3x 7x 7
803:11x 73
664:2x 2x 2x 83
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 83 = 747
Therefore, the value for common factors is 747.
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 = 175647840984/(1x747)
LCM = 175647840984/747
LCM = 235137672
Thus, we can understand that the LCM of 747,441,803,664 is 235137672.
