The LCM of 853,391,978,228,354 is 731307877548.
Find LCM of 853,391,978,228,354 with Prime Factorization
| 2 | 853, 391, 978, 228, 354 |
| 3 | 853, 391, 489, 114, 177 |
| 853, 391, 163, 38, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 853 x 391 x 163 x 38 x 59 = 731307877548
Therefore, the lowest common multiple of 853,391,978,228,354 is 731307877548.
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.
853 x 391 x 978 x 228 x 354 = 26327083591728
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.
853 : 1, 853
391 : 1, 17, 23, 391
978 : 1, 2, 3, 6, 163, 326, 489, 978
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,391,978,228,354, is 1.
Now, the common factors can be found like this.
853:853
391:17x 23
978:2x 3x 163
228:2x 2x 3x 19
354:2x 3x 59
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 = 26327083591728/(1x36)
LCM = 26327083591728/36
LCM = 731307877548
Thus, we can understand that the LCM of 853,391,978,228,354 is 731307877548.
