Given numbers are 378,602,854,908,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,602,854,908,815 is 366862694940.
Find LCM of 378,602,854,908,815 with Prime Factorization
| 2 | 378, 602, 854, 908, 815 |
| 7 | 189, 301, 427, 454, 815 |
| 27, 43, 61, 454, 815 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 27 x 43 x 61 x 454 x 815 = 366862694940
Therefore, the lowest common multiple of 378,602,854,908,815 is 366862694940.
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.
378 x 602 x 854 x 908 x 815 = 143810176416480
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
602 : 1, 2, 7, 14, 43, 86, 301, 602
854 : 1, 2, 7, 14, 61, 122, 427, 854
908 : 1, 2, 4, 227, 454, 908
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,602,854,908,815, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
602:2x 7x 43
854:2x 7x 61
908:2x 2x 227
815:5x 163
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 143810176416480/(1x392)
LCM = 143810176416480/392
LCM = 366862694940
Thus, we can understand that the LCM of 378,602,854,908,815 is 366862694940.
