Given numbers are 654,675,432,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,675,432,972 is 10594800.
Find LCM of 654,675,432,972 with Prime Factorization
| 2 | 654, 675, 432, 972 |
| 2 | 327, 675, 216, 486 |
| 3 | 327, 675, 108, 243 |
| 3 | 109, 225, 36, 81 |
| 3 | 109, 75, 12, 27 |
| 109, 25, 4, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 109 x 25 x 4 x 9 = 10594800
Therefore, the lowest common multiple of 654,675,432,972 is 10594800.
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.
654 x 675 x 432 x 972 = 185366620800
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,675,432,972, is 3.
Now, the common factors can be found like this.
654:2x 3x 109
675:3x 3x 3x 5x 5
432:2x 2x 2x 2x 3x 3x 3
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 3x 3x 3x 3x 3x 3 = 5832
Therefore, the value for common factors is 5832.
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 = 185366620800/(3x5832)
LCM = 185366620800/17496
LCM = 10594800
Thus, we can understand that the LCM of 654,675,432,972 is 10594800.
