Given numbers are 960,630,921,426
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 960,630,921,426 is 439427520.
Find LCM of 960,630,921,426 with Prime Factorization
| 2 | 960, 630, 921, 426 |
| 3 | 480, 315, 921, 213 |
| 5 | 160, 105, 307, 71 |
| 32, 21, 307, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 32 x 21 x 307 x 71 = 439427520
Therefore, the lowest common multiple of 960,630,921,426 is 439427520.
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.
960 x 630 x 921 x 426 = 237290860800
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.
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
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
921 : 1, 3, 307, 921
426 : 1, 2, 3, 6, 71, 142, 213, 426
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 960,630,921,426, is 3.
Now, the common factors can be found like this.
960:2x 2x 2x 2x 2x 2x 3x 5
630:2x 3x 3x 5x 7
921:3x 307
426:2x 3x 71
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 237290860800/(3x180)
LCM = 237290860800/540
LCM = 439427520
Thus, we can understand that the LCM of 960,630,921,426 is 439427520.
