Given numbers are 422,211,570
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,211,570 is 120270.
Find LCM of 422,211,570 with Prime Factorization
| 2 | 422, 211, 570 |
| 211 | 211, 211, 285 |
| 1, 1, 285 |
Multiply the prime numbers at the bottom and the left side.
2 x 211 x 1 x 1 x 285 = 120270
Therefore, the lowest common multiple of 422,211,570 is 120270.
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.
422 x 211 x 570 = 50753940
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.
422 : 1, 2, 211, 422
211 : 1, 211
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,211,570, is 1.
Now, the common factors can be found like this.
422:2x 211
211:211
570:2x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 211 = 422
Therefore, the value for common factors is 422.
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 = 50753940/(1x422)
LCM = 50753940/422
LCM = 120270
Thus, we can understand that the LCM of 422,211,570 is 120270.
