Find LCM of 629,693,618,407,642 with Prime Factorization
| 2 | 629, 693, 618, 407, 642 |
| 3 | 629, 693, 309, 407, 321 |
| 11 | 629, 231, 103, 407, 107 |
| 37 | 629, 21, 103, 37, 107 |
| 17, 21, 103, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 37 x 17 x 21 x 103 x 1 x 107 = 9608041674
Therefore, the lowest common multiple of 629,693,618,407,642 is 9608041674.
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.
629 x 693 x 618 x 407 x 642 = 70388513303724
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.
629 : 1, 17, 37, 629
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
618 : 1, 2, 3, 6, 103, 206, 309, 618
407 : 1, 11, 37, 407
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,693,618,407,642, is 1.
Now, the common factors can be found like this.
629:17x 37
693:3x 3x 7x 11
618:2x 3x 103
407:11x 37
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11x 37 = 7326
Therefore, the value for common factors is 7326.
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 = 70388513303724/(1x7326)
LCM = 70388513303724/7326
LCM = 9608041674
Thus, we can understand that the LCM of 629,693,618,407,642 is 9608041674.
