Find LCM of 721,444,372,206,169 with Prime Factorization
2 | 721, 444, 372, 206, 169 |
2 | 721, 222, 186, 103, 169 |
3 | 721, 111, 93, 103, 169 |
103 | 721, 37, 31, 103, 169 |
7, 37, 31, 1, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 103 x 7 x 37 x 31 x 1 x 169 = 1677129636
Therefore, the lowest common multiple of 721,444,372,206,169 is 1677129636.
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.
721 x 444 x 372 x 206 x 169 = 4145864460192
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.
721 : 1, 7, 103, 721
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
206 : 1, 2, 103, 206
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,444,372,206,169, is 1.
Now, the common factors can be found like this.
721:7x 103
444:2x 2x 3x 37
372:2x 2x 3x 31
206:2x 103
169:13x 13
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 103 = 2472
Therefore, the value for common factors is 2472.
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 = 4145864460192/(1x2472)
LCM = 4145864460192/2472
LCM = 1677129636
Thus, we can understand that the LCM of 721,444,372,206,169 is 1677129636.
