Given numbers are 962,660,740,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 962,660,740,871 is 21269820.
Find LCM of 962,660,740,871 with Prime Factorization
| 2 | 962, 660, 740, 871 |
| 2 | 481, 330, 370, 871 |
| 5 | 481, 165, 185, 871 |
| 13 | 481, 33, 37, 871 |
| 37 | 37, 33, 37, 67 |
| 1, 33, 1, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 37 x 1 x 33 x 1 x 67 = 21269820
Therefore, the lowest common multiple of 962,660,740,871 is 21269820.
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.
962 x 660 x 740 x 871 = 409231336800
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.
962 : 1, 2, 13, 26, 37, 74, 481, 962
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
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 962,660,740,871, is 1.
Now, the common factors can be found like this.
962:2x 13x 37
660:2x 2x 3x 5x 11
740:2x 2x 5x 37
871:13x 67
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 5x 13x 37 = 19240
Therefore, the value for common factors is 19240.
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 = 409231336800/(1x19240)
LCM = 409231336800/19240
LCM = 21269820
Thus, we can understand that the LCM of 962,660,740,871 is 21269820.
