Given numbers are 761,834,460,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 761,834,460,556 is 145975020.
Find LCM of 761,834,460,556 with Prime Factorization
| 2 | 761, 834, 460, 556 |
| 2 | 761, 417, 230, 278 |
| 139 | 761, 417, 115, 139 |
| 761, 3, 115, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 761 x 3 x 115 x 1 = 145975020
Therefore, the lowest common multiple of 761,834,460,556 is 145975020.
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.
761 x 834 x 460 x 556 = 162324222240
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.
761 : 1, 761
834 : 1, 2, 3, 6, 139, 278, 417, 834
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,834,460,556, is 1.
Now, the common factors can be found like this.
761:761
834:2x 3x 139
460:2x 2x 5x 23
556:2x 2x 139
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 2x 139 = 1112
Therefore, the value for common factors is 1112.
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 = 162324222240/(1x1112)
LCM = 162324222240/1112
LCM = 145975020
Thus, we can understand that the LCM of 761,834,460,556 is 145975020.
