Given numbers are 262,490,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 262,490,980 is 128380.
Find LCM of 262,490,980 with Prime Factorization
| 2 | 262, 490, 980 |
| 5 | 131, 245, 490 |
| 7 | 131, 49, 98 |
| 7 | 131, 7, 14 |
| 131, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 131 x 1 x 2 = 128380
Therefore, the lowest common multiple of 262,490,980 is 128380.
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 490 x 980 = 125812400
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
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,490,980, is 2.
Now, the common factors can be found like this.
262:2x 131
490:2x 5x 7x 7
980:2x 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 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 125812400/(2x490)
LCM = 125812400/980
LCM = 128380
Thus, we can understand that the LCM of 262,490,980 is 128380.
