Given numbers are 900,991,670,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 900,991,670,991 is 59757300.
Find LCM of 900,991,670,991 with Prime Factorization
| 2 | 900, 991, 670, 991 |
| 5 | 450, 991, 335, 991 |
| 991 | 90, 991, 67, 991 |
| 90, 1, 67, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 991 x 90 x 1 x 67 x 1 = 59757300
Therefore, the lowest common multiple of 900,991,670,991 is 59757300.
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.
900 x 991 x 670 x 991 = 592194843000
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
991 : 1, 991
670 : 1, 2, 5, 10, 67, 134, 335, 670
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,991,670,991, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
991:991
670:2x 5x 67
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 991 = 9910
Therefore, the value for common factors is 9910.
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 = 592194843000/(1x9910)
LCM = 592194843000/9910
LCM = 59757300
Thus, we can understand that the LCM of 900,991,670,991 is 59757300.
