Given numbers are 611,155,331,416,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,155,331,416,390 is 3009346080.
Find LCM of 611,155,331,416,390 with Prime Factorization
| 2 | 611, 155, 331, 416, 390 |
| 5 | 611, 155, 331, 208, 195 |
| 13 | 611, 31, 331, 208, 39 |
| 47, 31, 331, 16, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 47 x 31 x 331 x 16 x 3 = 3009346080
Therefore, the lowest common multiple of 611,155,331,416,390 is 3009346080.
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.
611 x 155 x 331 x 416 x 390 = 5085794875200
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.
611 : 1, 13, 47, 611
155 : 1, 5, 31, 155
331 : 1, 331
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,155,331,416,390, is 1.
Now, the common factors can be found like this.
611:13x 47
155:5x 31
331:331
416:2x 2x 2x 2x 2x 13
390:2x 3x 5x 13
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 13x 13 = 1690
Therefore, the value for common factors is 1690.
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 = 5085794875200/(1x1690)
LCM = 5085794875200/1690
LCM = 3009346080
Thus, we can understand that the LCM of 611,155,331,416,390 is 3009346080.
