Find LCM of 180,735,642,868,546 with Prime Factorization
| 2 | 180, 735, 642, 868, 546 |
| 2 | 90, 735, 321, 434, 273 |
| 3 | 45, 735, 321, 217, 273 |
| 5 | 15, 245, 107, 217, 91 |
| 7 | 3, 49, 107, 217, 91 |
| 3, 7, 107, 31, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 3 x 7 x 107 x 31 x 13 = 380327220
Therefore, the lowest common multiple of 180,735,642,868,546 is 380327220.
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.
180 x 735 x 642 x 868 x 546 = 40253832964800
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
642 : 1, 2, 3, 6, 107, 214, 321, 642
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,735,642,868,546, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
735:3x 5x 7x 7
642:2x 3x 107
868:2x 2x 7x 31
546:2x 3x 7x 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 2x 2x 2x 3x 3x 3x 5x 7x 7 = 105840
Therefore, the value for common factors is 105840.
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 = 40253832964800/(1x105840)
LCM = 40253832964800/105840
LCM = 380327220
Thus, we can understand that the LCM of 180,735,642,868,546 is 380327220.
