Given numbers are 761,121,861,442,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 761,121,861,442,561 is 35042529522.
Find LCM of 761,121,861,442,561 with Prime Factorization
3 | 761, 121, 861, 442, 561 |
11 | 761, 121, 287, 442, 187 |
17 | 761, 11, 287, 442, 17 |
761, 11, 287, 26, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 761 x 11 x 287 x 26 x 1 = 35042529522
Therefore, the lowest common multiple of 761,121,861,442,561 is 35042529522.
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.
761 x 121 x 861 x 442 x 561 = 19658859061842
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.
761 : 1, 761
121 : 1, 11, 121
861 : 1, 3, 7, 21, 41, 123, 287, 861
442 : 1, 2, 13, 17, 26, 34, 221, 442
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,121,861,442,561, is 1.
Now, the common factors can be found like this.
761:761
121:11x 11
861:3x 7x 41
442:2x 13x 17
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 17 = 561
Therefore, the value for common factors is 561.
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 = 19658859061842/(1x561)
LCM = 19658859061842/561
LCM = 35042529522
Thus, we can understand that the LCM of 761,121,861,442,561 is 35042529522.
