Given numbers are 359,194,174,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 359,194,174,420 is 424144140.
Find LCM of 359,194,174,420 with Prime Factorization
| 2 | 359, 194, 174, 420 |
| 3 | 359, 97, 87, 210 |
| 359, 97, 29, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 359 x 97 x 29 x 70 = 424144140
Therefore, the lowest common multiple of 359,194,174,420 is 424144140.
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.
359 x 194 x 174 x 420 = 5089729680
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.
359 : 1, 359
194 : 1, 2, 97, 194
174 : 1, 2, 3, 6, 29, 58, 87, 174
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 359,194,174,420, is 1.
Now, the common factors can be found like this.
359:359
194:2x 97
174:2x 3x 29
420:2x 2x 3x 5x 7
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 3 = 12
Therefore, the value for common factors is 12.
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 = 5089729680/(1x12)
LCM = 5089729680/12
LCM = 424144140
Thus, we can understand that the LCM of 359,194,174,420 is 424144140.
