Given numbers are 741,778,778,852
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,778,778,852 is 81862716.
Find LCM of 741,778,778,852 with Prime Factorization
| 2 | 741, 778, 778, 852 |
| 3 | 741, 389, 389, 426 |
| 389 | 247, 389, 389, 142 |
| 247, 1, 1, 142 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 389 x 247 x 1 x 1 x 142 = 81862716
Therefore, the lowest common multiple of 741,778,778,852 is 81862716.
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.
741 x 778 x 778 x 852 = 382135158288
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
778 : 1, 2, 389, 778
778 : 1, 2, 389, 778
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,778,778,852, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
778:2x 389
778:2x 389
852:2x 2x 3x 71
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 3x 389 = 4668
Therefore, the value for common factors is 4668.
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 = 382135158288/(1x4668)
LCM = 382135158288/4668
LCM = 81862716
Thus, we can understand that the LCM of 741,778,778,852 is 81862716.
