Given numbers are 490,245,606,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 490,245,606,580 is 8611260.
Find LCM of 490,245,606,580 with Prime Factorization
| 2 | 490, 245, 606, 580 |
| 5 | 245, 245, 303, 290 |
| 7 | 49, 49, 303, 58 |
| 7 | 7, 7, 303, 58 |
| 1, 1, 303, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 1 x 1 x 303 x 58 = 8611260
Therefore, the lowest common multiple of 490,245,606,580 is 8611260.
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.
490 x 245 x 606 x 580 = 42195174000
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.
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
245 : 1, 5, 7, 35, 49, 245
606 : 1, 2, 3, 6, 101, 202, 303, 606
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,245,606,580, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
245:5x 7x 7
606:2x 3x 101
580:2x 2x 5x 29
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 5x 5x 7x 7 = 4900
Therefore, the value for common factors is 4900.
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 = 42195174000/(1x4900)
LCM = 42195174000/4900
LCM = 8611260
Thus, we can understand that the LCM of 490,245,606,580 is 8611260.
