Given numbers are 431,716,319,308,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,716,319,308,680 is 117146127560.
Find LCM of 431,716,319,308,680 with Prime Factorization
| 2 | 431, 716, 319, 308, 680 |
| 2 | 431, 358, 319, 154, 340 |
| 11 | 431, 179, 319, 77, 170 |
| 431, 179, 29, 7, 170 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 431 x 179 x 29 x 7 x 170 = 117146127560
Therefore, the lowest common multiple of 431,716,319,308,680 is 117146127560.
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.
431 x 716 x 319 x 308 x 680 = 20617718450560
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.
431 : 1, 431
716 : 1, 2, 4, 179, 358, 716
319 : 1, 11, 29, 319
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,716,319,308,680, is 1.
Now, the common factors can be found like this.
431:431
716:2x 2x 179
319:11x 29
308:2x 2x 7x 11
680:2x 2x 2x 5x 17
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 11 = 176
Therefore, the value for common factors is 176.
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 = 20617718450560/(1x176)
LCM = 20617718450560/176
LCM = 117146127560
Thus, we can understand that the LCM of 431,716,319,308,680 is 117146127560.
