Given numbers are 741,551,871,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,551,871,688 is 990556944.
Find LCM of 741,551,871,688 with Prime Factorization
| 13 | 741, 551, 871, 688 |
| 19 | 57, 551, 67, 688 |
| 3, 29, 67, 688 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 3 x 29 x 67 x 688 = 990556944
Therefore, the lowest common multiple of 741,551,871,688 is 990556944.
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 551 x 871 x 688 = 244667565168
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
551 : 1, 19, 29, 551
871 : 1, 13, 67, 871
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,551,871,688, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
551:19x 29
871:13x 67
688:2x 2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 244667565168/(1x247)
LCM = 244667565168/247
LCM = 990556944
Thus, we can understand that the LCM of 741,551,871,688 is 990556944.
