The LCM of 372,907,217,420 is 11809140.
Find LCM of 372,907,217,420 with Prime Factorization
| 2 | 372, 907, 217, 420 |
| 2 | 186, 907, 217, 210 |
| 3 | 93, 907, 217, 105 |
| 7 | 31, 907, 217, 35 |
| 31 | 31, 907, 31, 5 |
| 1, 907, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 1 x 907 x 1 x 5 = 11809140
Therefore, the lowest common multiple of 372,907,217,420 is 11809140.
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.
372 x 907 x 217 x 420 = 30751000560
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
907 : 1, 907
217 : 1, 7, 31, 217
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 372,907,217,420, is 1.
Now, the common factors can be found like this.
372:2x 2x 3x 31
907:907
217:7x 31
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 3x 7x 31 = 2604
Therefore, the value for common factors is 2604.
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 = 30751000560/(1x2604)
LCM = 30751000560/2604
LCM = 11809140
Thus, we can understand that the LCM of 372,907,217,420 is 11809140.
