The LCM of 406,716,847,616 is 35174216.
Find LCM of 406,716,847,616 with Prime Factorization
| 2 | 406, 716, 847, 616 |
| 2 | 203, 358, 847, 308 |
| 7 | 203, 179, 847, 154 |
| 11 | 29, 179, 121, 22 |
| 29, 179, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 29 x 179 x 11 x 2 = 35174216
Therefore, the lowest common multiple of 406,716,847,616 is 35174216.
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.
406 x 716 x 847 x 616 = 151671219392
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
716 : 1, 2, 4, 179, 358, 716
847 : 1, 7, 11, 77, 121, 847
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,716,847,616, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
716:2x 2x 179
847:7x 11x 11
616:2x 2x 2x 7x 11
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 7x 11 = 4312
Therefore, the value for common factors is 4312.
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 = 151671219392/(1x4312)
LCM = 151671219392/4312
LCM = 35174216
Thus, we can understand that the LCM of 406,716,847,616 is 35174216.
