The LCM of 847,715,346,624 is 457176720.
Find LCM of 847,715,346,624 with Prime Factorization
| 2 | 847, 715, 346, 624 |
| 11 | 847, 715, 173, 312 |
| 13 | 77, 65, 173, 312 |
| 77, 5, 173, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 77 x 5 x 173 x 24 = 457176720
Therefore, the lowest common multiple of 847,715,346,624 is 457176720.
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.
847 x 715 x 346 x 624 = 130752541920
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.
847 : 1, 7, 11, 77, 121, 847
715 : 1, 5, 11, 13, 55, 65, 143, 715
346 : 1, 2, 173, 346
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,715,346,624, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
715:5x 11x 13
346:2x 173
624:2x 2x 2x 2x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 130752541920/(1x286)
LCM = 130752541920/286
LCM = 457176720
Thus, we can understand that the LCM of 847,715,346,624 is 457176720.
