Given numbers are 749,963,169,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,963,169,871 is 76328343.
Find LCM of 749,963,169,871 with Prime Factorization
| 13 | 749, 963, 169, 871 |
| 107 | 749, 963, 13, 67 |
| 7, 9, 13, 67 |
Multiply the prime numbers at the bottom and the left side.
13 x 107 x 7 x 9 x 13 x 67 = 76328343
Therefore, the lowest common multiple of 749,963,169,871 is 76328343.
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.
749 x 963 x 169 x 871 = 106172725113
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.
749 : 1, 7, 107, 749
963 : 1, 3, 9, 107, 321, 963
169 : 1, 13, 169
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,963,169,871, is 1.
Now, the common factors can be found like this.
749:7x 107
963:3x 3x 107
169:13x 13
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 107 = 1391
Therefore, the value for common factors is 1391.
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 = 106172725113/(1x1391)
LCM = 106172725113/1391
LCM = 76328343
Thus, we can understand that the LCM of 749,963,169,871 is 76328343.
