Find LCM of 755,154,504,786,142 with Prime Factorization
2 | 755, 154, 504, 786, 142 |
3 | 755, 77, 252, 393, 71 |
7 | 755, 77, 84, 131, 71 |
755, 11, 12, 131, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 755 x 11 x 12 x 131 x 71 = 38931381720
Therefore, the lowest common multiple of 755,154,504,786,142 is 38931381720.
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.
755 x 154 x 504 x 786 x 142 = 6540472128960
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.
755 : 1, 5, 151, 755
154 : 1, 2, 7, 11, 14, 22, 77, 154
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
786 : 1, 2, 3, 6, 131, 262, 393, 786
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,154,504,786,142, is 1.
Now, the common factors can be found like this.
755:5x 151
154:2x 7x 11
504:2x 2x 2x 3x 3x 7
786:2x 3x 131
142:2x 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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 6540472128960/(1x168)
LCM = 6540472128960/168
LCM = 38931381720
Thus, we can understand that the LCM of 755,154,504,786,142 is 38931381720.
