Given numbers are 315,862,154,724,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,862,154,724,217 is 33518206260.
Find LCM of 315,862,154,724,217 with Prime Factorization
| 2 | 315, 862, 154, 724, 217 |
| 7 | 315, 431, 77, 362, 217 |
| 45, 431, 11, 362, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 45 x 431 x 11 x 362 x 31 = 33518206260
Therefore, the lowest common multiple of 315,862,154,724,217 is 33518206260.
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.
315 x 862 x 154 x 724 x 217 = 6569568426960
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
862 : 1, 2, 431, 862
154 : 1, 2, 7, 11, 14, 22, 77, 154
724 : 1, 2, 4, 181, 362, 724
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,862,154,724,217, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
862:2x 431
154:2x 7x 11
724:2x 2x 181
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 = 6569568426960/(1x196)
LCM = 6569568426960/196
LCM = 33518206260
Thus, we can understand that the LCM of 315,862,154,724,217 is 33518206260.
