Given numbers are 991,803,146,685,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,803,146,685,440 is 4360836040.
Find LCM of 991,803,146,685,440 with Prime Factorization
| 2 | 991, 803, 146, 685, 440 |
| 5 | 991, 803, 73, 685, 220 |
| 11 | 991, 803, 73, 137, 44 |
| 73 | 991, 73, 73, 137, 4 |
| 991, 1, 1, 137, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 73 x 991 x 1 x 1 x 137 x 4 = 4360836040
Therefore, the lowest common multiple of 991,803,146,685,440 is 4360836040.
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 803 x 146 x 685 x 440 = 35017513401200
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
803 : 1, 11, 73, 803
146 : 1, 2, 73, 146
685 : 1, 5, 137, 685
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,803,146,685,440, is 1.
Now, the common factors can be found like this.
991:991
803:11x 73
146:2x 73
685:5x 137
440:2x 2x 2x 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 5x 11x 73 = 8030
Therefore, the value for common factors is 8030.
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 = 35017513401200/(1x8030)
LCM = 35017513401200/8030
LCM = 4360836040
Thus, we can understand that the LCM of 991,803,146,685,440 is 4360836040.
