Given numbers are 669,777,849,378,710
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,777,849,378,710 is 313338078270.
Find LCM of 669,777,849,378,710 with Prime Factorization
| 2 | 669, 777, 849, 378, 710 |
| 3 | 669, 777, 849, 189, 355 |
| 7 | 223, 259, 283, 63, 355 |
| 223, 37, 283, 9, 355 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 223 x 37 x 283 x 9 x 355 = 313338078270
Therefore, the lowest common multiple of 669,777,849,378,710 is 313338078270.
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.
669 x 777 x 849 x 378 x 710 = 118441793586060
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.
669 : 1, 3, 223, 669
777 : 1, 3, 7, 21, 37, 111, 259, 777
849 : 1, 3, 283, 849
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
710 : 1, 2, 5, 10, 71, 142, 355, 710
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,777,849,378,710, is 1.
Now, the common factors can be found like this.
669:3x 223
777:3x 7x 37
849:3x 283
378:2x 3x 3x 3x 7
710:2x 5x 71
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 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 118441793586060/(1x378)
LCM = 118441793586060/378
LCM = 313338078270
Thus, we can understand that the LCM of 669,777,849,378,710 is 313338078270.
