Given numbers are 659,890,760,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 659,890,760,660 is 1470967080.
Find LCM of 659,890,760,660 with Prime Factorization
| 2 | 659, 890, 760, 660 |
| 2 | 659, 445, 380, 330 |
| 5 | 659, 445, 190, 165 |
| 659, 89, 38, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 659 x 89 x 38 x 33 = 1470967080
Therefore, the lowest common multiple of 659,890,760,660 is 1470967080.
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.
659 x 890 x 760 x 660 = 294193416000
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.
659 : 1, 659
890 : 1, 2, 5, 10, 89, 178, 445, 890
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 659,890,760,660, is 1.
Now, the common factors can be found like this.
659:659
890:2x 5x 89
760:2x 2x 2x 5x 19
660:2x 2x 3x 5x 11
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 5 = 200
Therefore, the value for common factors is 200.
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 = 294193416000/(1x200)
LCM = 294193416000/200
LCM = 1470967080
Thus, we can understand that the LCM of 659,890,760,660 is 1470967080.
