Find LCM of 406,286,684,592,781 with Prime Factorization
2 | 406, 286, 684, 592, 781 |
2 | 203, 143, 342, 296, 781 |
11 | 203, 143, 171, 148, 781 |
203, 13, 171, 148, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 203 x 13 x 171 x 148 x 71 = 208645124688
Therefore, the lowest common multiple of 406,286,684,592,781 is 208645124688.
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 286 x 684 x 592 x 781 = 36721541945088
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,286,684,592,781, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
286:2x 11x 13
684:2x 2x 3x 3x 19
592:2x 2x 2x 2x 37
781:11x 71
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 11 = 176
Therefore, the value for common factors is 176.
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 = 36721541945088/(1x176)
LCM = 36721541945088/176
LCM = 208645124688
Thus, we can understand that the LCM of 406,286,684,592,781 is 208645124688.
