Given numbers are 619,707,469,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,707,469,871 is 381178343.
Find LCM of 619,707,469,871 with Prime Factorization
| 7 | 619, 707, 469, 871 |
| 67 | 619, 101, 67, 871 |
| 619, 101, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
7 x 67 x 619 x 101 x 1 x 13 = 381178343
Therefore, the lowest common multiple of 619,707,469,871 is 381178343.
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.
619 x 707 x 469 x 871 = 178772642867
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.
619 : 1, 619
707 : 1, 7, 101, 707
469 : 1, 7, 67, 469
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,707,469,871, is 1.
Now, the common factors can be found like this.
619:619
707:7x 101
469:7x 67
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.
7x 67 = 469
Therefore, the value for common factors is 469.
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 = 178772642867/(1x469)
LCM = 178772642867/469
LCM = 381178343
Thus, we can understand that the LCM of 619,707,469,871 is 381178343.
