Given numbers are 778,401,988,649,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,401,988,649,922 is 46110150605948.
Find LCM of 778,401,988,649,922 with Prime Factorization
| 2 | 778, 401, 988, 649, 922 |
| 389, 401, 494, 649, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 389 x 401 x 494 x 649 x 461 = 46110150605948
Therefore, the lowest common multiple of 778,401,988,649,922 is 46110150605948.
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 401 x 988 x 649 x 922 = 184440602423792
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
401 : 1, 401
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
649 : 1, 11, 59, 649
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,401,988,649,922, is 1.
Now, the common factors can be found like this.
778:2x 389
401:401
988:2x 2x 13x 19
649:11x 59
922:2x 461
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 = 184440602423792/(1x4)
LCM = 184440602423792/4
LCM = 46110150605948
Thus, we can understand that the LCM of 778,401,988,649,922 is 46110150605948.
