Given numbers are 310,578,120,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,578,120,980 is 52678920.
Find LCM of 310,578,120,980 with Prime Factorization
| 2 | 310, 578, 120, 980 |
| 2 | 155, 289, 60, 490 |
| 5 | 155, 289, 30, 245 |
| 31, 289, 6, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 31 x 289 x 6 x 49 = 52678920
Therefore, the lowest common multiple of 310,578,120,980 is 52678920.
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.
310 x 578 x 120 x 980 = 21071568000
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
578 : 1, 2, 17, 34, 289, 578
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
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 310,578,120,980, is 2.
Now, the common factors can be found like this.
310:2x 5x 31
578:2x 17x 17
120:2x 2x 2x 3x 5
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 5 = 200
Therefore, the value for common factors is 200.
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 = 21071568000/(2x200)
LCM = 21071568000/400
LCM = 52678920
Thus, we can understand that the LCM of 310,578,120,980 is 52678920.
