Find LCM of 973,981,836,655,180 with Prime Factorization
| 2 | 973, 981, 836, 655, 180 |
| 2 | 973, 981, 418, 655, 90 |
| 3 | 973, 981, 209, 655, 45 |
| 3 | 973, 327, 209, 655, 15 |
| 5 | 973, 109, 209, 655, 5 |
| 973, 109, 209, 131, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 973 x 109 x 209 x 131 x 1 = 522672228540
Therefore, the lowest common multiple of 973,981,836,655,180 is 522672228540.
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.
973 x 981 x 836 x 655 x 180 = 94081001137200
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.
973 : 1, 7, 139, 973
981 : 1, 3, 9, 109, 327, 981
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
655 : 1, 5, 131, 655
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,981,836,655,180, is 1.
Now, the common factors can be found like this.
973:7x 139
981:3x 3x 109
836:2x 2x 11x 19
655:5x 131
180:2x 2x 3x 3x 5
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 94081001137200/(1x180)
LCM = 94081001137200/180
LCM = 522672228540
Thus, we can understand that the LCM of 973,981,836,655,180 is 522672228540.
