Given numbers are 897,644,961,824,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,644,961,824,779 is 3873276849624.
Find LCM of 897,644,961,824,779 with Prime Factorization
| 2 | 897, 644, 961, 824, 779 |
| 2 | 897, 322, 961, 412, 779 |
| 23 | 897, 161, 961, 206, 779 |
| 39, 7, 961, 206, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 39 x 7 x 961 x 206 x 779 = 3873276849624
Therefore, the lowest common multiple of 897,644,961,824,779 is 3873276849624.
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.
897 x 644 x 961 x 824 x 779 = 356341470165408
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
961 : 1, 31, 961
824 : 1, 2, 4, 8, 103, 206, 412, 824
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,644,961,824,779, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
644:2x 2x 7x 23
961:31x 31
824:2x 2x 2x 103
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 23 = 92
Therefore, the value for common factors is 92.
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 = 356341470165408/(1x92)
LCM = 356341470165408/92
LCM = 3873276849624
Thus, we can understand that the LCM of 897,644,961,824,779 is 3873276849624.
