Find LCM of 158,497,721,504,774 with Prime Factorization
2 | 158, 497, 721, 504, 774 |
3 | 79, 497, 721, 252, 387 |
3 | 79, 497, 721, 84, 129 |
7 | 79, 497, 721, 28, 43 |
79, 71, 103, 4, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 79 x 71 x 103 x 4 x 43 = 12520499544
Therefore, the lowest common multiple of 158,497,721,504,774 is 12520499544.
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.
158 x 497 x 721 x 504 x 774 = 22086161195616
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.
158 : 1, 2, 79, 158
497 : 1, 7, 71, 497
721 : 1, 7, 103, 721
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,497,721,504,774, is 1.
Now, the common factors can be found like this.
158:2x 79
497:7x 71
721:7x 103
504:2x 2x 2x 3x 3x 7
774:2x 3x 3x 43
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 3x 3x 7x 7 = 1764
Therefore, the value for common factors is 1764.
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 = 22086161195616/(1x1764)
LCM = 22086161195616/1764
LCM = 12520499544
Thus, we can understand that the LCM of 158,497,721,504,774 is 12520499544.
