Given numbers are 178,551,558,435
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,551,558,435 is 136818810.
Find LCM of 178,551,558,435 with Prime Factorization
| 2 | 178, 551, 558, 435 |
| 3 | 89, 551, 279, 435 |
| 29 | 89, 551, 93, 145 |
| 89, 19, 93, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 89 x 19 x 93 x 5 = 136818810
Therefore, the lowest common multiple of 178,551,558,435 is 136818810.
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.
178 x 551 x 558 x 435 = 23806472940
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.
178 : 1, 2, 89, 178
551 : 1, 19, 29, 551
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,551,558,435, is 1.
Now, the common factors can be found like this.
178:2x 89
551:19x 29
558:2x 3x 3x 31
435:3x 5x 29
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 29 = 174
Therefore, the value for common factors is 174.
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 = 23806472940/(1x174)
LCM = 23806472940/174
LCM = 136818810
Thus, we can understand that the LCM of 178,551,558,435 is 136818810.
