Given numbers are 743,878,644,969,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,878,644,969,451 is 91799331857772.
Find LCM of 743,878,644,969,451 with Prime Factorization
2 | 743, 878, 644, 969, 451 |
743, 439, 322, 969, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 743 x 439 x 322 x 969 x 451 = 91799331857772
Therefore, the lowest common multiple of 743,878,644,969,451 is 91799331857772.
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.
743 x 878 x 644 x 969 x 451 = 183598663715544
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.
743 : 1, 743
878 : 1, 2, 439, 878
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
969 : 1, 3, 17, 19, 51, 57, 323, 969
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,878,644,969,451, is 1.
Now, the common factors can be found like this.
743:743
878:2x 439
644:2x 2x 7x 23
969:3x 17x 19
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 183598663715544/(1x2)
LCM = 183598663715544/2
LCM = 91799331857772
Thus, we can understand that the LCM of 743,878,644,969,451 is 91799331857772.
