Given numbers are 393,220,670,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,220,670,389 is 2253406980.
Find LCM of 393,220,670,389 with Prime Factorization
| 2 | 393, 220, 670, 389 |
| 5 | 393, 110, 335, 389 |
| 393, 22, 67, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 393 x 22 x 67 x 389 = 2253406980
Therefore, the lowest common multiple of 393,220,670,389 is 2253406980.
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.
393 x 220 x 670 x 389 = 22534069800
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.
393 : 1, 3, 131, 393
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
670 : 1, 2, 5, 10, 67, 134, 335, 670
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,220,670,389, is 1.
Now, the common factors can be found like this.
393:3x 131
220:2x 2x 5x 11
670:2x 5x 67
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 22534069800/(1x10)
LCM = 22534069800/10
LCM = 2253406980
Thus, we can understand that the LCM of 393,220,670,389 is 2253406980.
