Given numbers are 643,955,923,603,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,955,923,603,804 is 1367078171940.
Find LCM of 643,955,923,603,804 with Prime Factorization
3 | 643, 955, 923, 603, 804 |
67 | 643, 955, 923, 201, 268 |
643, 955, 923, 3, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 67 x 643 x 955 x 923 x 3 x 4 = 1367078171940
Therefore, the lowest common multiple of 643,955,923,603,804 is 1367078171940.
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.
643 x 955 x 923 x 603 x 804 = 274782712559940
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.
643 : 1, 643
955 : 1, 5, 191, 955
923 : 1, 13, 71, 923
603 : 1, 3, 9, 67, 201, 603
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,955,923,603,804, is 1.
Now, the common factors can be found like this.
643:643
955:5x 191
923:13x 71
603:3x 3x 67
804:2x 2x 3x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 67 = 201
Therefore, the value for common factors is 201.
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 = 274782712559940/(1x201)
LCM = 274782712559940/201
LCM = 1367078171940
Thus, we can understand that the LCM of 643,955,923,603,804 is 1367078171940.
