Given numbers are 111,570,362,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,570,362,420 is 53442060.
Find LCM of 111,570,362,420 with Prime Factorization
| 2 | 111, 570, 362, 420 |
| 3 | 111, 285, 181, 210 |
| 5 | 37, 95, 181, 70 |
| 37, 19, 181, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 19 x 181 x 14 = 53442060
Therefore, the lowest common multiple of 111,570,362,420 is 53442060.
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.
111 x 570 x 362 x 420 = 9619570800
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.
111 : 1, 3, 37, 111
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
362 : 1, 2, 181, 362
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 111,570,362,420, is 1.
Now, the common factors can be found like this.
111:3x 37
570:2x 3x 5x 19
362:2x 181
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 9619570800/(1x180)
LCM = 9619570800/180
LCM = 53442060
Thus, we can understand that the LCM of 111,570,362,420 is 53442060.
