Given numbers are 872,215,178,602
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,215,178,602 is 116800040.
Find LCM of 872,215,178,602 with Prime Factorization
| 2 | 872, 215, 178, 602 |
| 43 | 436, 215, 89, 301 |
| 436, 5, 89, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 436 x 5 x 89 x 7 = 116800040
Therefore, the lowest common multiple of 872,215,178,602 is 116800040.
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.
872 x 215 x 178 x 602 = 20089606880
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
215 : 1, 5, 43, 215
178 : 1, 2, 89, 178
602 : 1, 2, 7, 14, 43, 86, 301, 602
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,215,178,602, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
215:5x 43
178:2x 89
602:2x 7x 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 43 = 172
Therefore, the value for common factors is 172.
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 = 20089606880/(1x172)
LCM = 20089606880/172
LCM = 116800040
Thus, we can understand that the LCM of 872,215,178,602 is 116800040.
