Find LCM of 162,614,447,420,972 with Prime Factorization
2 | 162, 614, 447, 420, 972 |
2 | 81, 307, 447, 210, 486 |
3 | 81, 307, 447, 105, 243 |
3 | 27, 307, 149, 35, 81 |
3 | 9, 307, 149, 35, 27 |
3 | 3, 307, 149, 35, 9 |
1, 307, 149, 35, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 1 x 307 x 149 x 35 x 3 = 1556176860
Therefore, the lowest common multiple of 162,614,447,420,972 is 1556176860.
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.
162 x 614 x 447 x 420 x 972 = 18151246895040
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
614 : 1, 2, 307, 614
447 : 1, 3, 149, 447
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,614,447,420,972, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
614:2x 307
447:3x 149
420:2x 2x 3x 5x 7
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 3 = 11664
Therefore, the value for common factors is 11664.
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 = 18151246895040/(1x11664)
LCM = 18151246895040/11664
LCM = 1556176860
Thus, we can understand that the LCM of 162,614,447,420,972 is 1556176860.
