Given numbers are 685,247,121,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,247,121,418 is 40945190.
Find LCM of 685,247,121,418 with Prime Factorization
11 | 685, 247, 121, 418 |
19 | 685, 247, 11, 38 |
685, 13, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 685 x 13 x 11 x 2 = 40945190
Therefore, the lowest common multiple of 685,247,121,418 is 40945190.
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.
685 x 247 x 121 x 418 = 8557544710
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.
685 : 1, 5, 137, 685
247 : 1, 13, 19, 247
121 : 1, 11, 121
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,247,121,418, is 1.
Now, the common factors can be found like this.
685:5x 137
247:13x 19
121:11x 11
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 8557544710/(1x209)
LCM = 8557544710/209
LCM = 40945190
Thus, we can understand that the LCM of 685,247,121,418 is 40945190.
