Find LCM of 644,219,529,658,656 with Prime Factorization
2 | 644, 219, 529, 658, 656 |
2 | 322, 219, 529, 329, 328 |
7 | 161, 219, 529, 329, 164 |
23 | 23, 219, 529, 47, 164 |
1, 219, 23, 47, 164 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 23 x 1 x 219 x 23 x 47 x 164 = 25003426224
Therefore, the lowest common multiple of 644,219,529,658,656 is 25003426224.
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.
644 x 219 x 529 x 658 x 656 = 32204412976512
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
219 : 1, 3, 73, 219
529 : 1, 23, 529
658 : 1, 2, 7, 14, 47, 94, 329, 658
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,219,529,658,656, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
219:3x 73
529:23x 23
658:2x 7x 47
656:2x 2x 2x 2x 41
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 7x 23 = 1288
Therefore, the value for common factors is 1288.
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 = 32204412976512/(1x1288)
LCM = 32204412976512/1288
LCM = 25003426224
Thus, we can understand that the LCM of 644,219,529,658,656 is 25003426224.
