Given numbers are 398,722,921,836,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,722,921,836,549 is 532750265388.
Find LCM of 398,722,921,836,549 with Prime Factorization
| 2 | 398, 722, 921, 836, 549 |
| 3 | 199, 361, 921, 418, 549 |
| 19 | 199, 361, 307, 418, 183 |
| 199, 19, 307, 22, 183 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 199 x 19 x 307 x 22 x 183 = 532750265388
Therefore, the lowest common multiple of 398,722,921,836,549 is 532750265388.
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.
398 x 722 x 921 x 836 x 549 = 121467060508464
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.
398 : 1, 2, 199, 398
722 : 1, 2, 19, 38, 361, 722
921 : 1, 3, 307, 921
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,722,921,836,549, is 1.
Now, the common factors can be found like this.
398:2x 199
722:2x 19x 19
921:3x 307
836:2x 2x 11x 19
549:3x 3x 61
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 19 = 228
Therefore, the value for common factors is 228.
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 = 121467060508464/(1x228)
LCM = 121467060508464/228
LCM = 532750265388
Thus, we can understand that the LCM of 398,722,921,836,549 is 532750265388.
