Find LCM of 733,221,858,477,423 with Prime Factorization
| 3 | 733, 221, 858, 477, 423 |
| 3 | 733, 221, 286, 159, 141 |
| 13 | 733, 221, 286, 53, 47 |
| 733, 17, 22, 53, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 733 x 17 x 22 x 53 x 47 = 79897863474
Therefore, the lowest common multiple of 733,221,858,477,423 is 79897863474.
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.
733 x 221 x 858 x 477 x 423 = 28044150079374
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.
733 : 1, 733
221 : 1, 13, 17, 221
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
477 : 1, 3, 9, 53, 159, 477
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 733,221,858,477,423, is 1.
Now, the common factors can be found like this.
733:733
221:13x 17
858:2x 3x 11x 13
477:3x 3x 53
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 13 = 351
Therefore, the value for common factors is 351.
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 = 28044150079374/(1x351)
LCM = 28044150079374/351
LCM = 79897863474
Thus, we can understand that the LCM of 733,221,858,477,423 is 79897863474.
