Find LCM of 840,968,196,363 with Prime Factorization
| 2 | 840, 968, 196, 363 |
| 2 | 420, 484, 98, 363 |
| 2 | 210, 242, 49, 363 |
| 3 | 105, 121, 49, 363 |
| 7 | 35, 121, 49, 121 |
| 11 | 5, 121, 7, 121 |
| 11 | 5, 11, 7, 11 |
| 5, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 11 x 5 x 1 x 7 x 1 = 711480
Therefore, the lowest common multiple of 840,968,196,363 is 711480.
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.
840 x 968 x 196 x 363 = 57851861760
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.
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
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
363 : 1, 3, 11, 33, 121, 363
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,968,196,363, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
968:2x 2x 2x 11x 11
196:2x 2x 7x 7
363:3x 11x 11
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 7x 11x 11 = 81312
Therefore, the value for common factors is 81312.
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 = 57851861760/(1x81312)
LCM = 57851861760/81312
LCM = 711480
Thus, we can understand that the LCM of 840,968,196,363 is 711480.
