Given numbers are 684,744,291,143,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,744,291,143,685 is 402945337080.
Find LCM of 684,744,291,143,685 with Prime Factorization
| 2 | 684, 744, 291, 143, 685 |
| 2 | 342, 372, 291, 143, 685 |
| 3 | 171, 186, 291, 143, 685 |
| 57, 62, 97, 143, 685 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 57 x 62 x 97 x 143 x 685 = 402945337080
Therefore, the lowest common multiple of 684,744,291,143,685 is 402945337080.
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.
684 x 744 x 291 x 143 x 685 = 14506032134880
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
291 : 1, 3, 97, 291
143 : 1, 11, 13, 143
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,744,291,143,685, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
744:2x 2x 2x 3x 31
291:3x 97
143:11x 13
685:5x 137
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 14506032134880/(1x36)
LCM = 14506032134880/36
LCM = 402945337080
Thus, we can understand that the LCM of 684,744,291,143,685 is 402945337080.
