Given numbers are 561,748,817,535
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,748,817,535 is 980841180.
Find LCM of 561,748,817,535 with Prime Factorization
| 11 | 561, 748, 817, 535 |
| 17 | 51, 68, 817, 535 |
| 3, 4, 817, 535 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 3 x 4 x 817 x 535 = 980841180
Therefore, the lowest common multiple of 561,748,817,535 is 980841180.
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 748 x 817 x 535 = 183417300660
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
817 : 1, 19, 43, 817
535 : 1, 5, 107, 535
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,748,817,535, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
748:2x 2x 11x 17
817:19x 43
535:5x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 183417300660/(1x187)
LCM = 183417300660/187
LCM = 980841180
Thus, we can understand that the LCM of 561,748,817,535 is 980841180.
