Given numbers are 177,120,442,786,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 177,120,442,786,722 is 73995281880.
Find LCM of 177,120,442,786,722 with Prime Factorization
| 2 | 177, 120, 442, 786, 722 |
| 3 | 177, 60, 221, 393, 361 |
| 59, 20, 221, 131, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 59 x 20 x 221 x 131 x 361 = 73995281880
Therefore, the lowest common multiple of 177,120,442,786,722 is 73995281880.
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.
177 x 120 x 442 x 786 x 722 = 5327660295360
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.
177 : 1, 3, 59, 177
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
442 : 1, 2, 13, 17, 26, 34, 221, 442
786 : 1, 2, 3, 6, 131, 262, 393, 786
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,120,442,786,722, is 1.
Now, the common factors can be found like this.
177:3x 59
120:2x 2x 2x 3x 5
442:2x 13x 17
786:2x 3x 131
722:2x 19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 5327660295360/(1x72)
LCM = 5327660295360/72
LCM = 73995281880
Thus, we can understand that the LCM of 177,120,442,786,722 is 73995281880.
