Given numbers are 669,472,705,611,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,472,705,611,285 is 18328753560.
Find LCM of 669,472,705,611,285 with Prime Factorization
3 | 669, 472, 705, 611, 285 |
5 | 223, 472, 235, 611, 95 |
47 | 223, 472, 47, 611, 19 |
223, 472, 1, 13, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 47 x 223 x 472 x 1 x 13 x 19 = 18328753560
Therefore, the lowest common multiple of 669,472,705,611,285 is 18328753560.
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.
669 x 472 x 705 x 611 x 285 = 38765313779400
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.
669 : 1, 3, 223, 669
472 : 1, 2, 4, 8, 59, 118, 236, 472
705 : 1, 3, 5, 15, 47, 141, 235, 705
611 : 1, 13, 47, 611
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,472,705,611,285, is 1.
Now, the common factors can be found like this.
669:3x 223
472:2x 2x 2x 59
705:3x 5x 47
611:13x 47
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 47 = 2115
Therefore, the value for common factors is 2115.
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 = 38765313779400/(1x2115)
LCM = 38765313779400/2115
LCM = 18328753560
Thus, we can understand that the LCM of 669,472,705,611,285 is 18328753560.
