The LCM of 210,348,961,140 is 11704980.
Find LCM of 210,348,961,140 with Prime Factorization
| 2 | 210, 348, 961, 140 |
| 2 | 105, 174, 961, 70 |
| 3 | 105, 87, 961, 35 |
| 5 | 35, 29, 961, 35 |
| 7 | 7, 29, 961, 7 |
| 1, 29, 961, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 1 x 29 x 961 x 1 = 11704980
Therefore, the lowest common multiple of 210,348,961,140 is 11704980.
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.
210 x 348 x 961 x 140 = 9832183200
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
961 : 1, 31, 961
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,348,961,140, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
348:2x 2x 3x 29
961:31x 31
140:2x 2x 5x 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 3x 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 9832183200/(1x840)
LCM = 9832183200/840
LCM = 11704980
Thus, we can understand that the LCM of 210,348,961,140 is 11704980.
