Given numbers are 328,779,697,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 328,779,697,931 is 5191256.
Find LCM of 328,779,697,931 with Prime Factorization
| 19 | 328, 779, 697, 931 |
| 41 | 328, 41, 697, 49 |
| 8, 1, 17, 49 |
Multiply the prime numbers at the bottom and the left side.
19 x 41 x 8 x 1 x 17 x 49 = 5191256
Therefore, the lowest common multiple of 328,779,697,931 is 5191256.
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.
328 x 779 x 697 x 931 = 165803525384
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
779 : 1, 19, 41, 779
697 : 1, 17, 41, 697
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,779,697,931, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
779:19x 41
697:17x 41
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 41x 41 = 31939
Therefore, the value for common factors is 31939.
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 = 165803525384/(1x31939)
LCM = 165803525384/31939
LCM = 5191256
Thus, we can understand that the LCM of 328,779,697,931 is 5191256.
