Given numbers are 775,542,142,220,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,542,142,220,284 is 656118100.
Find LCM of 775,542,142,220,284 with Prime Factorization
| 2 | 775, 542, 142, 220, 284 |
| 2 | 775, 271, 71, 110, 142 |
| 5 | 775, 271, 71, 55, 71 |
| 71 | 155, 271, 71, 11, 71 |
| 155, 271, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 71 x 155 x 271 x 1 x 11 x 1 = 656118100
Therefore, the lowest common multiple of 775,542,142,220,284 is 656118100.
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.
775 x 542 x 142 x 220 x 284 = 3726750808000
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.
775 : 1, 5, 25, 31, 155, 775
542 : 1, 2, 271, 542
142 : 1, 2, 71, 142
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,542,142,220,284, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
542:2x 271
142:2x 71
220:2x 2x 5x 11
284:2x 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 2x 5x 71 = 5680
Therefore, the value for common factors is 5680.
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 = 3726750808000/(1x5680)
LCM = 3726750808000/5680
LCM = 656118100
Thus, we can understand that the LCM of 775,542,142,220,284 is 656118100.
