The LCM of 168,721,993,603,310 is 178444125720.
Find LCM of 168,721,993,603,310 with Prime Factorization
2 | 168, 721, 993, 603, 310 |
3 | 84, 721, 993, 603, 155 |
7 | 28, 721, 331, 201, 155 |
4, 103, 331, 201, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 4 x 103 x 331 x 201 x 155 = 178444125720
Therefore, the lowest common multiple of 168,721,993,603,310 is 178444125720.
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.
168 x 721 x 993 x 603 x 310 = 22483959840720
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
721 : 1, 7, 103, 721
993 : 1, 3, 331, 993
603 : 1, 3, 9, 67, 201, 603
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,721,993,603,310, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
721:7x 103
993:3x 331
603:3x 3x 67
310:2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 22483959840720/(1x126)
LCM = 22483959840720/126
LCM = 178444125720
Thus, we can understand that the LCM of 168,721,993,603,310 is 178444125720.
