Find LCM of 960,482,402,840,421 with Prime Factorization
| 2 | 960, 482, 402, 840, 421 |
| 2 | 480, 241, 201, 420, 421 |
| 2 | 240, 241, 201, 210, 421 |
| 3 | 120, 241, 201, 105, 421 |
| 5 | 40, 241, 67, 35, 421 |
| 8, 241, 67, 7, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 8 x 241 x 67 x 7 x 421 = 45681800640
Therefore, the lowest common multiple of 960,482,402,840,421 is 45681800640.
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 482 x 402 x 840 x 421 = 65781792921600
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
482 : 1, 2, 241, 482
402 : 1, 2, 3, 6, 67, 134, 201, 402
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 960,482,402,840,421, is 1.
Now, the common factors can be found like this.
960:2x 2x 2x 2x 2x 2x 3x 5
482:2x 241
402:2x 3x 67
840:2x 2x 2x 3x 5x 7
421:421
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 2x 3x 3x 5 = 1440
Therefore, the value for common factors is 1440.
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 = 65781792921600/(1x1440)
LCM = 65781792921600/1440
LCM = 45681800640
Thus, we can understand that the LCM of 960,482,402,840,421 is 45681800640.
