Given numbers are 689,435,117,631,635
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,435,117,631,635 is 72054782865.
Find LCM of 689,435,117,631,635 with Prime Factorization
3 | 689, 435, 117, 631, 635 |
5 | 689, 145, 39, 631, 635 |
13 | 689, 29, 39, 631, 127 |
53, 29, 3, 631, 127 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 53 x 29 x 3 x 631 x 127 = 72054782865
Therefore, the lowest common multiple of 689,435,117,631,635 is 72054782865.
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.
689 x 435 x 117 x 631 x 635 = 14050682658675
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.
689 : 1, 13, 53, 689
435 : 1, 3, 5, 15, 29, 87, 145, 435
117 : 1, 3, 9, 13, 39, 117
631 : 1, 631
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,435,117,631,635, is 1.
Now, the common factors can be found like this.
689:13x 53
435:3x 5x 29
117:3x 3x 13
631:631
635:5x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 14050682658675/(1x195)
LCM = 14050682658675/195
LCM = 72054782865
Thus, we can understand that the LCM of 689,435,117,631,635 is 72054782865.
