The LCM of 690,836,551,965,361 is 30671448060.
Find LCM of 690,836,551,965,361 with Prime Factorization
| 2 | 690, 836, 551, 965, 361 |
| 5 | 345, 418, 551, 965, 361 |
| 19 | 69, 418, 551, 193, 361 |
| 69, 22, 29, 193, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 69 x 22 x 29 x 193 x 19 = 30671448060
Therefore, the lowest common multiple of 690,836,551,965,361 is 30671448060.
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.
690 x 836 x 551 x 965 x 361 = 110723927496600
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
551 : 1, 19, 29, 551
965 : 1, 5, 193, 965
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,836,551,965,361, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
836:2x 2x 11x 19
551:19x 29
965:5x 193
361:19x 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 5x 19x 19 = 3610
Therefore, the value for common factors is 3610.
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 = 110723927496600/(1x3610)
LCM = 110723927496600/3610
LCM = 30671448060
Thus, we can understand that the LCM of 690,836,551,965,361 is 30671448060.
