Given numbers are 715,897,943,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,897,943,666 is 449047170.
Find LCM of 715,897,943,666 with Prime Factorization
3 | 715, 897, 943, 666 |
13 | 715, 299, 943, 222 |
23 | 55, 23, 943, 222 |
55, 1, 41, 222 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 55 x 1 x 41 x 222 = 449047170
Therefore, the lowest common multiple of 715,897,943,666 is 449047170.
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.
715 x 897 x 943 x 666 = 402795311490
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
897 : 1, 3, 13, 23, 39, 69, 299, 897
943 : 1, 23, 41, 943
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,897,943,666, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
897:3x 13x 23
943:23x 41
666:2x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 23 = 897
Therefore, the value for common factors is 897.
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 = 402795311490/(1x897)
LCM = 402795311490/897
LCM = 449047170
Thus, we can understand that the LCM of 715,897,943,666 is 449047170.
