Given numbers are 262,289,764,505,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 262,289,764,505,490 is 715731209620.
Find LCM of 262,289,764,505,490 with Prime Factorization
| 2 | 262, 289, 764, 505, 490 |
| 5 | 131, 289, 382, 505, 245 |
| 131, 289, 382, 101, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 131 x 289 x 382 x 101 x 49 = 715731209620
Therefore, the lowest common multiple of 262,289,764,505,490 is 715731209620.
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.
262 x 289 x 764 x 505 x 490 = 14314624192400
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.
262 : 1, 2, 131, 262
289 : 1, 17, 289
764 : 1, 2, 4, 191, 382, 764
505 : 1, 5, 101, 505
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,289,764,505,490, is 1.
Now, the common factors can be found like this.
262:2x 131
289:17x 17
764:2x 2x 191
505:5x 101
490:2x 5x 7x 7
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 5 = 20
Therefore, the value for common factors is 20.
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 = 14314624192400/(1x20)
LCM = 14314624192400/20
LCM = 715731209620
Thus, we can understand that the LCM of 262,289,764,505,490 is 715731209620.
