Find LCM of 174,817,989,661,858 with Prime Factorization
2 | 174, 817, 989, 661, 858 |
3 | 87, 817, 989, 661, 429 |
43 | 29, 817, 989, 661, 143 |
29, 19, 23, 661, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 29 x 19 x 23 x 661 x 143 = 309055614582
Therefore, the lowest common multiple of 174,817,989,661,858 is 309055614582.
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.
174 x 817 x 989 x 661 x 858 = 79736348562156
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.
174 : 1, 2, 3, 6, 29, 58, 87, 174
817 : 1, 19, 43, 817
989 : 1, 23, 43, 989
661 : 1, 661
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,817,989,661,858, is 1.
Now, the common factors can be found like this.
174:2x 3x 29
817:19x 43
989:23x 43
661:661
858:2x 3x 11x 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 3x 43 = 258
Therefore, the value for common factors is 258.
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 = 79736348562156/(1x258)
LCM = 79736348562156/258
LCM = 309055614582
Thus, we can understand that the LCM of 174,817,989,661,858 is 309055614582.
