Given numbers are 991,255,190,302
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,255,190,302 is 1450021290.
Find LCM of 991,255,190,302 with Prime Factorization
| 2 | 991, 255, 190, 302 |
| 5 | 991, 255, 95, 151 |
| 991, 51, 19, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 991 x 51 x 19 x 151 = 1450021290
Therefore, the lowest common multiple of 991,255,190,302 is 1450021290.
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.
991 x 255 x 190 x 302 = 14500212900
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.
991 : 1, 991
255 : 1, 3, 5, 15, 17, 51, 85, 255
190 : 1, 2, 5, 10, 19, 38, 95, 190
302 : 1, 2, 151, 302
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,255,190,302, is 1.
Now, the common factors can be found like this.
991:991
255:3x 5x 17
190:2x 5x 19
302:2x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 14500212900/(1x10)
LCM = 14500212900/10
LCM = 1450021290
Thus, we can understand that the LCM of 991,255,190,302 is 1450021290.
