The LCM of 142,545,693,165 is 53631270.
Find LCM of 142,545,693,165 with Prime Factorization
| 3 | 142, 545, 693, 165 |
| 5 | 142, 545, 231, 55 |
| 11 | 142, 109, 231, 11 |
| 142, 109, 21, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 142 x 109 x 21 x 1 = 53631270
Therefore, the lowest common multiple of 142,545,693,165 is 53631270.
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.
142 x 545 x 693 x 165 = 8849159550
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.
142 : 1, 2, 71, 142
545 : 1, 5, 109, 545
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,545,693,165, is 1.
Now, the common factors can be found like this.
142:2x 71
545:5x 109
693:3x 3x 7x 11
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 8849159550/(1x165)
LCM = 8849159550/165
LCM = 53631270
Thus, we can understand that the LCM of 142,545,693,165 is 53631270.
