Given numbers are 530,422,399,371
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 530,422,399,371 is 44620170.
Find LCM of 530,422,399,371 with Prime Factorization
| 2 | 530, 422, 399, 371 |
| 7 | 265, 211, 399, 371 |
| 53 | 265, 211, 57, 53 |
| 5, 211, 57, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 53 x 5 x 211 x 57 x 1 = 44620170
Therefore, the lowest common multiple of 530,422,399,371 is 44620170.
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.
530 x 422 x 399 x 371 = 33108166140
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.
530 : 1, 2, 5, 10, 53, 106, 265, 530
422 : 1, 2, 211, 422
399 : 1, 3, 7, 19, 21, 57, 133, 399
371 : 1, 7, 53, 371
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,422,399,371, is 1.
Now, the common factors can be found like this.
530:2x 5x 53
422:2x 211
399:3x 7x 19
371:7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 53 = 742
Therefore, the value for common factors is 742.
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 = 33108166140/(1x742)
LCM = 33108166140/742
LCM = 44620170
Thus, we can understand that the LCM of 530,422,399,371 is 44620170.
