Find LCM of 971,210,660,836,798 with Prime Factorization
| 2 | 971, 210, 660, 836, 798 |
| 2 | 971, 105, 330, 418, 399 |
| 3 | 971, 105, 165, 209, 399 |
| 5 | 971, 35, 55, 209, 133 |
| 7 | 971, 7, 11, 209, 133 |
| 11 | 971, 1, 11, 209, 19 |
| 19 | 971, 1, 1, 19, 19 |
| 971, 1, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 19 x 971 x 1 x 1 x 1 x 1 = 85234380
Therefore, the lowest common multiple of 971,210,660,836,798 is 85234380.
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.
971 x 210 x 660 x 836 x 798 = 89782486516800
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.
971 : 1, 971
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,210,660,836,798, is 1.
Now, the common factors can be found like this.
971:971
210:2x 3x 5x 7
660:2x 2x 3x 5x 11
836:2x 2x 11x 19
798:2x 3x 7x 19
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 3x 5x 7x 11x 19 = 1053360
Therefore, the value for common factors is 1053360.
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 = 89782486516800/(1x1053360)
LCM = 89782486516800/1053360
LCM = 85234380
Thus, we can understand that the LCM of 971,210,660,836,798 is 85234380.
