Given numbers are 572,357,561,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 572,357,561,423 is 28792764.
Find LCM of 572,357,561,423 with Prime Factorization
| 3 | 572, 357, 561, 423 |
| 11 | 572, 119, 187, 141 |
| 17 | 52, 119, 17, 141 |
| 52, 7, 1, 141 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 52 x 7 x 1 x 141 = 28792764
Therefore, the lowest common multiple of 572,357,561,423 is 28792764.
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.
572 x 357 x 561 x 423 = 48458221812
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.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
357 : 1, 3, 7, 17, 21, 51, 119, 357
561 : 1, 3, 11, 17, 33, 51, 187, 561
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,357,561,423, is 1.
Now, the common factors can be found like this.
572:2x 2x 11x 13
357:3x 7x 17
561:3x 11x 17
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 17 = 1683
Therefore, the value for common factors is 1683.
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 = 48458221812/(1x1683)
LCM = 48458221812/1683
LCM = 28792764
Thus, we can understand that the LCM of 572,357,561,423 is 28792764.
