Given numbers are 280,721,172,117,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,721,172,117,217 is 4497915240.
Find LCM of 280,721,172,117,217 with Prime Factorization
2 | 280, 721, 172, 117, 217 |
2 | 140, 721, 86, 117, 217 |
7 | 70, 721, 43, 117, 217 |
10, 103, 43, 117, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 10 x 103 x 43 x 117 x 31 = 4497915240
Therefore, the lowest common multiple of 280,721,172,117,217 is 4497915240.
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.
280 x 721 x 172 x 117 x 217 = 881591387040
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
721 : 1, 7, 103, 721
172 : 1, 2, 4, 43, 86, 172
117 : 1, 3, 9, 13, 39, 117
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,721,172,117,217, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
721:7x 103
172:2x 2x 43
117:3x 3x 13
217:7x 31
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 = 881591387040/(1x196)
LCM = 881591387040/196
LCM = 4497915240
Thus, we can understand that the LCM of 280,721,172,117,217 is 4497915240.
