Given numbers are 561,637,779,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,637,779,572 is 1113524412.
Find LCM of 561,637,779,572 with Prime Factorization
| 11 | 561, 637, 779, 572 |
| 13 | 51, 637, 779, 52 |
| 51, 49, 779, 4 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 51 x 49 x 779 x 4 = 1113524412
Therefore, the lowest common multiple of 561,637,779,572 is 1113524412.
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.
561 x 637 x 779 x 572 = 159233990916
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
637 : 1, 7, 13, 49, 91, 637
779 : 1, 19, 41, 779
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,637,779,572, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
637:7x 7x 13
779:19x 41
572:2x 2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 159233990916/(1x143)
LCM = 159233990916/143
LCM = 1113524412
Thus, we can understand that the LCM of 561,637,779,572 is 1113524412.
