Find LCM of 693,551,638,429,865 with Prime Factorization
| 3 | 693, 551, 638, 429, 865 |
| 11 | 231, 551, 638, 143, 865 |
| 29 | 21, 551, 58, 13, 865 |
| 21, 19, 2, 13, 865 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 29 x 21 x 19 x 2 x 13 x 865 = 8587649070
Therefore, the lowest common multiple of 693,551,638,429,865 is 8587649070.
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.
693 x 551 x 638 x 429 x 865 = 90402181759890
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
551 : 1, 19, 29, 551
638 : 1, 2, 11, 22, 29, 58, 319, 638
429 : 1, 3, 11, 13, 33, 39, 143, 429
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,551,638,429,865, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
551:19x 29
638:2x 11x 29
429:3x 11x 13
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11x 29 = 10527
Therefore, the value for common factors is 10527.
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 = 90402181759890/(1x10527)
LCM = 90402181759890/10527
LCM = 8587649070
Thus, we can understand that the LCM of 693,551,638,429,865 is 8587649070.
