Given numbers are 777,581,962,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,581,962,931 is 223009878.
Find LCM of 777,581,962,931 with Prime Factorization
| 7 | 777, 581, 962, 931 |
| 37 | 111, 83, 962, 133 |
| 3, 83, 26, 133 |
Multiply the prime numbers at the bottom and the left side.
7 x 37 x 3 x 83 x 26 x 133 = 223009878
Therefore, the lowest common multiple of 777,581,962,931 is 223009878.
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.
777 x 581 x 962 x 931 = 404316908814
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
581 : 1, 7, 83, 581
962 : 1, 2, 13, 26, 37, 74, 481, 962
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 777,581,962,931, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
581:7x 83
962:2x 13x 37
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.
7x 7x 37 = 1813
Therefore, the value for common factors is 1813.
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 = 404316908814/(1x1813)
LCM = 404316908814/1813
LCM = 223009878
Thus, we can understand that the LCM of 777,581,962,931 is 223009878.
