Given numbers are 894,357,196,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,357,196,423 is 210005964.
Find LCM of 894,357,196,423 with Prime Factorization
| 2 | 894, 357, 196, 423 |
| 3 | 447, 357, 98, 423 |
| 7 | 149, 119, 98, 141 |
| 149, 17, 14, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 149 x 17 x 14 x 141 = 210005964
Therefore, the lowest common multiple of 894,357,196,423 is 210005964.
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.
894 x 357 x 196 x 423 = 26460751464
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
357 : 1, 3, 7, 17, 21, 51, 119, 357
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,357,196,423, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
357:3x 7x 17
196:2x 2x 7x 7
423:3x 3x 47
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 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 26460751464/(1x126)
LCM = 26460751464/126
LCM = 210005964
Thus, we can understand that the LCM of 894,357,196,423 is 210005964.
