Given numbers are 699,689,860,458
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,689,860,458 is 94848470340.
Find LCM of 699,689,860,458 with Prime Factorization
2 | 699, 689, 860, 458 |
699, 689, 430, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 699 x 689 x 430 x 229 = 94848470340
Therefore, the lowest common multiple of 699,689,860,458 is 94848470340.
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.
699 x 689 x 860 x 458 = 189696940680
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.
699 : 1, 3, 233, 699
689 : 1, 13, 53, 689
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
458 : 1, 2, 229, 458
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,689,860,458, is 1.
Now, the common factors can be found like this.
699:3x 233
689:13x 53
860:2x 2x 5x 43
458:2x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 189696940680/(1x2)
LCM = 189696940680/2
LCM = 94848470340
Thus, we can understand that the LCM of 699,689,860,458 is 94848470340.
