Given numbers are 660,573,406,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,573,406,728 is 665344680.
Find LCM of 660,573,406,728 with Prime Factorization
2 | 660, 573, 406, 728 |
2 | 330, 573, 203, 364 |
3 | 165, 573, 203, 182 |
7 | 55, 191, 203, 182 |
55, 191, 29, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 55 x 191 x 29 x 26 = 665344680
Therefore, the lowest common multiple of 660,573,406,728 is 665344680.
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.
660 x 573 x 406 x 728 = 111777906240
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.
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
573 : 1, 3, 191, 573
406 : 1, 2, 7, 14, 29, 58, 203, 406
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,573,406,728, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
573:3x 191
406:2x 7x 29
728:2x 2x 2x 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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 111777906240/(1x168)
LCM = 111777906240/168
LCM = 665344680
Thus, we can understand that the LCM of 660,573,406,728 is 665344680.
