Find LCM of 355,240,132,145,645 with Prime Factorization
2 | 355, 240, 132, 145, 645 |
2 | 355, 120, 66, 145, 645 |
3 | 355, 60, 33, 145, 645 |
5 | 355, 20, 11, 145, 215 |
71, 4, 11, 29, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 71 x 4 x 11 x 29 x 43 = 233737680
Therefore, the lowest common multiple of 355,240,132,145,645 is 233737680.
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.
355 x 240 x 132 x 145 x 645 = 1051819560000
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.
355 : 1, 5, 71, 355
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
145 : 1, 5, 29, 145
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,240,132,145,645, is 1.
Now, the common factors can be found like this.
355:5x 71
240:2x 2x 2x 2x 3x 5
132:2x 2x 3x 11
145:5x 29
645:3x 5x 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 5x 5x 5 = 4500
Therefore, the value for common factors is 4500.
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 = 1051819560000/(1x4500)
LCM = 1051819560000/4500
LCM = 233737680
Thus, we can understand that the LCM of 355,240,132,145,645 is 233737680.
