Given numbers are 355,490,209,524,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,490,209,524,247 is 24765400660.
Find LCM of 355,490,209,524,247 with Prime Factorization
| 2 | 355, 490, 209, 524, 247 |
| 5 | 355, 245, 209, 262, 247 |
| 19 | 71, 49, 209, 262, 247 |
| 71, 49, 11, 262, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 71 x 49 x 11 x 262 x 13 = 24765400660
Therefore, the lowest common multiple of 355,490,209,524,247 is 24765400660.
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.
355 x 490 x 209 x 524 x 247 = 4705426125400
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.
355 : 1, 5, 71, 355
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
209 : 1, 11, 19, 209
524 : 1, 2, 4, 131, 262, 524
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,490,209,524,247, is 1.
Now, the common factors can be found like this.
355:5x 71
490:2x 5x 7x 7
209:11x 19
524:2x 2x 131
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 19 = 190
Therefore, the value for common factors is 190.
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 = 4705426125400/(1x190)
LCM = 4705426125400/190
LCM = 24765400660
Thus, we can understand that the LCM of 355,490,209,524,247 is 24765400660.
