Given numbers are 142,575,381,535,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,575,381,535,990 is 109844643150.
Find LCM of 142,575,381,535,990 with Prime Factorization
| 2 | 142, 575, 381, 535, 990 |
| 3 | 71, 575, 381, 535, 495 |
| 5 | 71, 575, 127, 535, 165 |
| 71, 115, 127, 107, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 71 x 115 x 127 x 107 x 33 = 109844643150
Therefore, the lowest common multiple of 142,575,381,535,990 is 109844643150.
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 575 x 381 x 535 x 990 = 16476696472500
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
575 : 1, 5, 23, 25, 115, 575
381 : 1, 3, 127, 381
535 : 1, 5, 107, 535
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,575,381,535,990, is 1.
Now, the common factors can be found like this.
142:2x 71
575:5x 5x 23
381:3x 127
535:5x 107
990:2x 3x 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.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 16476696472500/(1x150)
LCM = 16476696472500/150
LCM = 109844643150
Thus, we can understand that the LCM of 142,575,381,535,990 is 109844643150.
