Given numbers are 421,290,508,812,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,290,508,812,517 is 112228302340.
Find LCM of 421,290,508,812,517 with Prime Factorization
| 2 | 421, 290, 508, 812, 517 |
| 2 | 421, 145, 254, 406, 517 |
| 29 | 421, 145, 127, 203, 517 |
| 421, 5, 127, 7, 517 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 421 x 5 x 127 x 7 x 517 = 112228302340
Therefore, the lowest common multiple of 421,290,508,812,517 is 112228302340.
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.
421 x 290 x 508 x 812 x 517 = 26036966142880
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.
421 : 1, 421
290 : 1, 2, 5, 10, 29, 58, 145, 290
508 : 1, 2, 4, 127, 254, 508
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,290,508,812,517, is 1.
Now, the common factors can be found like this.
421:421
290:2x 5x 29
508:2x 2x 127
812:2x 2x 7x 29
517:11x 47
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 29 = 232
Therefore, the value for common factors is 232.
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 = 26036966142880/(1x232)
LCM = 26036966142880/232
LCM = 112228302340
Thus, we can understand that the LCM of 421,290,508,812,517 is 112228302340.
