The LCM of 621,897,314,426 is 179979462.
Find LCM of 621,897,314,426 with Prime Factorization
| 2 | 621, 897, 314, 426 |
| 3 | 621, 897, 157, 213 |
| 23 | 207, 299, 157, 71 |
| 9, 13, 157, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 9 x 13 x 157 x 71 = 179979462
Therefore, the lowest common multiple of 621,897,314,426 is 179979462.
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.
621 x 897 x 314 x 426 = 74511497268
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
897 : 1, 3, 13, 23, 39, 69, 299, 897
314 : 1, 2, 157, 314
426 : 1, 2, 3, 6, 71, 142, 213, 426
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,897,314,426, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
897:3x 13x 23
314:2x 157
426:2x 3x 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 23 = 414
Therefore, the value for common factors is 414.
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 = 74511497268/(1x414)
LCM = 74511497268/414
LCM = 179979462
Thus, we can understand that the LCM of 621,897,314,426 is 179979462.
