Given numbers are 778,818,916,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,818,916,818 is 145736516.
Find LCM of 778,818,916,818 with Prime Factorization
| 2 | 778, 818, 916, 818 |
| 409 | 389, 409, 458, 409 |
| 389, 1, 458, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 409 x 389 x 1 x 458 x 1 = 145736516
Therefore, the lowest common multiple of 778,818,916,818 is 145736516.
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.
778 x 818 x 916 x 818 = 476849880352
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.
778 : 1, 2, 389, 778
818 : 1, 2, 409, 818
916 : 1, 2, 4, 229, 458, 916
818 : 1, 2, 409, 818
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,818,916,818, is 2.
Now, the common factors can be found like this.
778:2x 389
818:2x 409
916:2x 2x 229
818:2x 409
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 409 = 1636
Therefore, the value for common factors is 1636.
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 = 476849880352/(2x1636)
LCM = 476849880352/3272
LCM = 145736516
Thus, we can understand that the LCM of 778,818,916,818 is 145736516.
