Given numbers are 836,116,176,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,116,176,421 is 40826896.
Find LCM of 836,116,176,421 with Prime Factorization
| 2 | 836, 116, 176, 421 |
| 2 | 418, 58, 88, 421 |
| 11 | 209, 29, 44, 421 |
| 19, 29, 4, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 29 x 4 x 421 = 40826896
Therefore, the lowest common multiple of 836,116,176,421 is 40826896.
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.
836 x 116 x 176 x 421 = 7185533696
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
116 : 1, 2, 4, 29, 58, 116
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,116,176,421, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
116:2x 2x 29
176:2x 2x 2x 2x 11
421:421
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 11 = 176
Therefore, the value for common factors is 176.
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 = 7185533696/(1x176)
LCM = 7185533696/176
LCM = 40826896
Thus, we can understand that the LCM of 836,116,176,421 is 40826896.
