Find LCM of 222,660,900,972,901 with Prime Factorization
| 2 | 222, 660, 900, 972, 901 |
| 2 | 111, 330, 450, 486, 901 |
| 3 | 111, 165, 225, 243, 901 |
| 3 | 37, 55, 75, 81, 901 |
| 5 | 37, 55, 25, 27, 901 |
| 37, 11, 5, 27, 901 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 37 x 11 x 5 x 27 x 901 = 8910980100
Therefore, the lowest common multiple of 222,660,900,972,901 is 8910980100.
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.
222 x 660 x 900 x 972 x 901 = 115486302096000
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.
222 : 1, 2, 3, 6, 37, 74, 111, 222
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,660,900,972,901, is 1.
Now, the common factors can be found like this.
222:2x 3x 37
660:2x 2x 3x 5x 11
900:2x 2x 3x 3x 5x 5
972:2x 2x 3x 3x 3x 3x 3
901:17x 53
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 2x 2x 3x 3x 3x 3x 5 = 12960
Therefore, the value for common factors is 12960.
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 = 115486302096000/(1x12960)
LCM = 115486302096000/12960
LCM = 8910980100
Thus, we can understand that the LCM of 222,660,900,972,901 is 8910980100.
