Given numbers are 847,697,258,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,697,258,387 is 456937866.
Find LCM of 847,697,258,387 with Prime Factorization
3 | 847, 697, 258, 387 |
43 | 847, 697, 86, 129 |
847, 697, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 847 x 697 x 2 x 3 = 456937866
Therefore, the lowest common multiple of 847,697,258,387 is 456937866.
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.
847 x 697 x 258 x 387 = 58944984714
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.
847 : 1, 7, 11, 77, 121, 847
697 : 1, 17, 41, 697
258 : 1, 2, 3, 6, 43, 86, 129, 258
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,697,258,387, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
697:17x 41
258:2x 3x 43
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 58944984714/(1x129)
LCM = 58944984714/129
LCM = 456937866
Thus, we can understand that the LCM of 847,697,258,387 is 456937866.
