Find LCM of 408,931,539,856 with Prime Factorization
| 2 | 408, 931, 539, 856 |
| 2 | 204, 931, 539, 428 |
| 2 | 102, 931, 539, 214 |
| 7 | 51, 931, 539, 107 |
| 7 | 51, 133, 77, 107 |
| 51, 19, 11, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 51 x 19 x 11 x 107 = 447081096
Therefore, the lowest common multiple of 408,931,539,856 is 447081096.
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.
408 x 931 x 539 x 856 = 175255789632
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
931 : 1, 7, 19, 49, 133, 931
539 : 1, 7, 11, 49, 77, 539
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,931,539,856, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
931:7x 7x 19
539:7x 7x 11
856:2x 2x 2x 107
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 7 = 392
Therefore, the value for common factors is 392.
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 = 175255789632/(1x392)
LCM = 175255789632/392
LCM = 447081096
Thus, we can understand that the LCM of 408,931,539,856 is 447081096.
