Given numbers are 773,788,813,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 773,788,813,820 is 101519651460.
Find LCM of 773,788,813,820 with Prime Factorization
| 2 | 773, 788, 813, 820 |
| 2 | 773, 394, 813, 410 |
| 773, 197, 813, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 773 x 197 x 813 x 205 = 101519651460
Therefore, the lowest common multiple of 773,788,813,820 is 101519651460.
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.
773 x 788 x 813 x 820 = 406078605840
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.
773 : 1, 773
788 : 1, 2, 4, 197, 394, 788
813 : 1, 3, 271, 813
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 773,788,813,820, is 1.
Now, the common factors can be found like this.
773:773
788:2x 2x 197
813:3x 271
820:2x 2x 5x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 406078605840/(1x4)
LCM = 406078605840/4
LCM = 101519651460
Thus, we can understand that the LCM of 773,788,813,820 is 101519651460.
