Given numbers are 778,949,507,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,949,507,312 is 115178232.
Find LCM of 778,949,507,312 with Prime Factorization
| 2 | 778, 949, 507, 312 |
| 3 | 389, 949, 507, 156 |
| 13 | 389, 949, 169, 52 |
| 389, 73, 13, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 389 x 73 x 13 x 4 = 115178232
Therefore, the lowest common multiple of 778,949,507,312 is 115178232.
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 949 x 507 x 312 = 116790727248
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
949 : 1, 13, 73, 949
507 : 1, 3, 13, 39, 169, 507
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,949,507,312, is 1.
Now, the common factors can be found like this.
778:2x 389
949:13x 73
507:3x 13x 13
312:2x 2x 2x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 13 = 1014
Therefore, the value for common factors is 1014.
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 = 116790727248/(1x1014)
LCM = 116790727248/1014
LCM = 115178232
Thus, we can understand that the LCM of 778,949,507,312 is 115178232.
