Given numbers are 260,407,320,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 260,407,320,676 is 22010560.
Find LCM of 260,407,320,676 with Prime Factorization
| 2 | 260, 407, 320, 676 |
| 2 | 130, 407, 160, 338 |
| 5 | 65, 407, 80, 169 |
| 13 | 13, 407, 16, 169 |
| 1, 407, 16, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 1 x 407 x 16 x 13 = 22010560
Therefore, the lowest common multiple of 260,407,320,676 is 22010560.
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.
260 x 407 x 320 x 676 = 22890982400
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
407 : 1, 11, 37, 407
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,407,320,676, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
407:11x 37
320:2x 2x 2x 2x 2x 2x 5
676:2x 2x 13x 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 2x 2x 2x 5x 13 = 1040
Therefore, the value for common factors is 1040.
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 = 22890982400/(1x1040)
LCM = 22890982400/1040
LCM = 22010560
Thus, we can understand that the LCM of 260,407,320,676 is 22010560.
