Find LCM of 555,715,644,689,777 with Prime Factorization
3 | 555, 715, 644, 689, 777 |
5 | 185, 715, 644, 689, 259 |
7 | 37, 143, 644, 689, 259 |
13 | 37, 143, 92, 689, 37 |
37 | 37, 11, 92, 53, 37 |
1, 11, 92, 53, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 13 x 37 x 1 x 11 x 92 x 53 x 1 = 2708886180
Therefore, the lowest common multiple of 555,715,644,689,777 is 2708886180.
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.
555 x 715 x 644 x 689 x 777 = 136812296520900
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
715 : 1, 5, 11, 13, 55, 65, 143, 715
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
689 : 1, 13, 53, 689
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,715,644,689,777, is 1.
Now, the common factors can be found like this.
555:3x 5x 37
715:5x 11x 13
644:2x 2x 7x 23
689:13x 53
777:3x 7x 37
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 7x 13x 37 = 50505
Therefore, the value for common factors is 50505.
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 = 136812296520900/(1x50505)
LCM = 136812296520900/50505
LCM = 2708886180
Thus, we can understand that the LCM of 555,715,644,689,777 is 2708886180.
