Given numbers are 310,646,332,398,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,646,332,398,697 is 135615471220.
Find LCM of 310,646,332,398,697 with Prime Factorization
| 2 | 310, 646, 332, 398, 697 |
| 17 | 155, 323, 166, 199, 697 |
| 155, 19, 166, 199, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 155 x 19 x 166 x 199 x 41 = 135615471220
Therefore, the lowest common multiple of 310,646,332,398,697 is 135615471220.
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.
310 x 646 x 332 x 398 x 697 = 18443704085920
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
646 : 1, 2, 17, 19, 34, 38, 323, 646
332 : 1, 2, 4, 83, 166, 332
398 : 1, 2, 199, 398
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,646,332,398,697, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
646:2x 17x 19
332:2x 2x 83
398:2x 199
697:17x 41
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 17 = 136
Therefore, the value for common factors is 136.
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 = 18443704085920/(1x136)
LCM = 18443704085920/136
LCM = 135615471220
Thus, we can understand that the LCM of 310,646,332,398,697 is 135615471220.
