Given numbers are 728,653,960,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,653,960,370 is 2110704960.
Find LCM of 728,653,960,370 with Prime Factorization
| 2 | 728, 653, 960, 370 |
| 2 | 364, 653, 480, 185 |
| 2 | 182, 653, 240, 185 |
| 5 | 91, 653, 120, 185 |
| 91, 653, 24, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 91 x 653 x 24 x 37 = 2110704960
Therefore, the lowest common multiple of 728,653,960,370 is 2110704960.
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.
728 x 653 x 960 x 370 = 168856396800
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
653 : 1, 653
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,653,960,370, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
653:653
960:2x 2x 2x 2x 2x 2x 3x 5
370:2x 5x 37
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 5 = 80
Therefore, the value for common factors is 80.
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 = 168856396800/(1x80)
LCM = 168856396800/80
LCM = 2110704960
Thus, we can understand that the LCM of 728,653,960,370 is 2110704960.
