Given numbers are 250,310,980,415,550
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 250,310,980,415,550 is 693423500.
Find LCM of 250,310,980,415,550 with Prime Factorization
| 2 | 250, 310, 980, 415, 550 |
| 5 | 125, 155, 490, 415, 275 |
| 5 | 25, 31, 98, 83, 55 |
| 5, 31, 98, 83, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 5 x 31 x 98 x 83 x 11 = 693423500
Therefore, the lowest common multiple of 250,310,980,415,550 is 693423500.
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.
250 x 310 x 980 x 415 x 550 = 17335587500000
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.
250 : 1, 2, 5, 10, 25, 50, 125, 250
310 : 1, 2, 5, 10, 31, 62, 155, 310
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
415 : 1, 5, 83, 415
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 250,310,980,415,550, is 5.
Now, the common factors can be found like this.
250:2x 5x 5x 5
310:2x 5x 31
980:2x 2x 5x 7x 7
415:5x 83
550:2x 5x 5x 11
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 2x 5x 5x 5x 5 = 5000
Therefore, the value for common factors is 5000.
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 = 17335587500000/(5x5000)
LCM = 17335587500000/25000
LCM = 693423500
Thus, we can understand that the LCM of 250,310,980,415,550 is 693423500.
