Given numbers are 500,490,703,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 500,490,703,980 is 17223500.
Find LCM of 500,490,703,980 with Prime Factorization
| 2 | 500, 490, 703, 980 |
| 2 | 250, 245, 703, 490 |
| 5 | 125, 245, 703, 245 |
| 7 | 25, 49, 703, 49 |
| 7 | 25, 7, 703, 7 |
| 25, 1, 703, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 7 x 25 x 1 x 703 x 1 = 17223500
Therefore, the lowest common multiple of 500,490,703,980 is 17223500.
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.
500 x 490 x 703 x 980 = 168790300000
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.
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
703 : 1, 19, 37, 703
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 500,490,703,980, is 1.
Now, the common factors can be found like this.
500:2x 2x 5x 5x 5
490:2x 5x 7x 7
703:19x 37
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 2x 2x 5x 5x 7x 7 = 9800
Therefore, the value for common factors is 9800.
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 = 168790300000/(1x9800)
LCM = 168790300000/9800
LCM = 17223500
Thus, we can understand that the LCM of 500,490,703,980 is 17223500.
