Given numbers are 32,78,98,49,509
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 32,78,98,49,509 is 31126368.
Find LCM of 32,78,98,49,509 with Prime Factorization
| 2 | 32, 78, 98, 49, 509 |
| 7 | 16, 39, 49, 49, 509 |
| 7 | 16, 39, 7, 7, 509 |
| 16, 39, 1, 1, 509 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 16 x 39 x 1 x 1 x 509 = 31126368
Therefore, the lowest common multiple of 32,78,98,49,509 is 31126368.
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.
32 x 78 x 98 x 49 x 509 = 6100768128
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.
32 : 1, 2, 4, 8, 16, 32
78 : 1, 2, 3, 6, 13, 26, 39, 78
98 : 1, 2, 7, 14, 49, 98
49 : 1, 7, 49
509 : 1, 509
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 32,78,98,49,509, is 1.
Now, the common factors can be found like this.
32:2x 2x 2x 2x 2
78:2x 3x 13
98:2x 7x 7
49:7x 7
509:509
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 6100768128/(1x196)
LCM = 6100768128/196
LCM = 31126368
Thus, we can understand that the LCM of 32,78,98,49,509 is 31126368.
