Find LCM of 617,984,656,556 with Prime Factorization
| 2 | 617, 984, 656, 556 |
| 2 | 617, 492, 328, 278 |
| 2 | 617, 246, 164, 139 |
| 41 | 617, 123, 82, 139 |
| 617, 3, 2, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 41 x 617 x 3 x 2 x 139 = 168781584
Therefore, the lowest common multiple of 617,984,656,556 is 168781584.
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.
617 x 984 x 656 x 556 = 221441438208
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.
617 : 1, 617
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,984,656,556, is 1.
Now, the common factors can be found like this.
617:617
984:2x 2x 2x 3x 41
656:2x 2x 2x 2x 41
556:2x 2x 139
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 2x 2x 41 = 1312
Therefore, the value for common factors is 1312.
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 = 221441438208/(1x1312)
LCM = 221441438208/1312
LCM = 168781584
Thus, we can understand that the LCM of 617,984,656,556 is 168781584.
