Find LCM of 981,522,655,892,556 with Prime Factorization
| 2 | 981, 522, 655, 892, 556 |
| 2 | 981, 261, 655, 446, 278 |
| 3 | 981, 261, 655, 223, 139 |
| 3 | 327, 87, 655, 223, 139 |
| 109, 29, 655, 223, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 109 x 29 x 655 x 223 x 139 = 2310404170860
Therefore, the lowest common multiple of 981,522,655,892,556 is 2310404170860.
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.
981 x 522 x 655 x 892 x 556 = 166349100301920
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.
981 : 1, 3, 9, 109, 327, 981
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
655 : 1, 5, 131, 655
892 : 1, 2, 4, 223, 446, 892
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 981,522,655,892,556, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
522:2x 3x 3x 29
655:5x 131
892:2x 2x 223
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 166349100301920/(1x72)
LCM = 166349100301920/72
LCM = 2310404170860
Thus, we can understand that the LCM of 981,522,655,892,556 is 2310404170860.
