Given numbers are 939,145,420,300
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,145,420,300 is 19061700.
Find LCM of 939,145,420,300 with Prime Factorization
| 2 | 939, 145, 420, 300 |
| 2 | 939, 145, 210, 150 |
| 3 | 939, 145, 105, 75 |
| 5 | 313, 145, 35, 25 |
| 313, 29, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 313 x 29 x 7 x 5 = 19061700
Therefore, the lowest common multiple of 939,145,420,300 is 19061700.
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.
939 x 145 x 420 x 300 = 17155530000
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.
939 : 1, 3, 313, 939
145 : 1, 5, 29, 145
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
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,145,420,300, is 1.
Now, the common factors can be found like this.
939:3x 313
145:5x 29
420:2x 2x 3x 5x 7
300:2x 2x 3x 5x 5
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 3x 3x 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 17155530000/(1x900)
LCM = 17155530000/900
LCM = 19061700
Thus, we can understand that the LCM of 939,145,420,300 is 19061700.
