Find LCM of 556,697,634,486,918 with Prime Factorization
| 2 | 556, 697, 634, 486, 918 |
| 3 | 278, 697, 317, 243, 459 |
| 3 | 278, 697, 317, 81, 153 |
| 3 | 278, 697, 317, 27, 51 |
| 17 | 278, 697, 317, 9, 17 |
| 278, 41, 317, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 17 x 278 x 41 x 317 x 9 x 1 = 29851977492
Therefore, the lowest common multiple of 556,697,634,486,918 is 29851977492.
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.
556 x 697 x 634 x 486 x 918 = 109616461350624
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.
556 : 1, 2, 4, 139, 278, 556
697 : 1, 17, 41, 697
634 : 1, 2, 317, 634
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,697,634,486,918, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
697:17x 41
634:2x 317
486:2x 3x 3x 3x 3x 3
918:2x 3x 3x 3x 17
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 3x 3x 3x 17 = 3672
Therefore, the value for common factors is 3672.
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 = 109616461350624/(1x3672)
LCM = 109616461350624/3672
LCM = 29851977492
Thus, we can understand that the LCM of 556,697,634,486,918 is 29851977492.
