Given numbers are 630,964,420,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,964,420,940 is 14272020.
Find LCM of 630,964,420,940 with Prime Factorization
| 2 | 630, 964, 420, 940 |
| 2 | 315, 482, 210, 470 |
| 3 | 315, 241, 105, 235 |
| 5 | 35, 241, 105, 235 |
| 7 | 7, 241, 21, 47 |
| 1, 241, 3, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 1 x 241 x 3 x 47 = 14272020
Therefore, the lowest common multiple of 630,964,420,940 is 14272020.
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.
630 x 964 x 420 x 940 = 239769936000
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
964 : 1, 2, 4, 241, 482, 964
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,964,420,940, is 2.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
964:2x 2x 241
420:2x 2x 3x 5x 7
940:2x 2x 5x 47
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 2x 3x 5x 5x 7 = 8400
Therefore, the value for common factors is 8400.
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 = 239769936000/(2x8400)
LCM = 239769936000/16800
LCM = 14272020
Thus, we can understand that the LCM of 630,964,420,940 is 14272020.
