Given numbers are 441,656,703,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 441,656,703,628 is 31929888816.
Find LCM of 441,656,703,628 with Prime Factorization
| 2 | 441, 656, 703, 628 |
| 2 | 441, 328, 703, 314 |
| 441, 164, 703, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 441 x 164 x 703 x 157 = 31929888816
Therefore, the lowest common multiple of 441,656,703,628 is 31929888816.
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.
441 x 656 x 703 x 628 = 127719555264
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
703 : 1, 19, 37, 703
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,656,703,628, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
656:2x 2x 2x 2x 41
703:19x 37
628:2x 2x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 127719555264/(1x4)
LCM = 127719555264/4
LCM = 31929888816
Thus, we can understand that the LCM of 441,656,703,628 is 31929888816.
