Given numbers are 785,860,327,654,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,860,327,654,921 is 13554522780.
Find LCM of 785,860,327,654,921 with Prime Factorization
| 2 | 785, 860, 327, 654, 921 |
| 3 | 785, 430, 327, 327, 921 |
| 5 | 785, 430, 109, 109, 307 |
| 109 | 157, 86, 109, 109, 307 |
| 157, 86, 1, 1, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 109 x 157 x 86 x 1 x 1 x 307 = 13554522780
Therefore, the lowest common multiple of 785,860,327,654,921 is 13554522780.
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.
785 x 860 x 327 x 654 x 921 = 132969868471800
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.
785 : 1, 5, 157, 785
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
327 : 1, 3, 109, 327
654 : 1, 2, 3, 6, 109, 218, 327, 654
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,860,327,654,921, is 1.
Now, the common factors can be found like this.
785:5x 157
860:2x 2x 5x 43
327:3x 109
654:2x 3x 109
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 109 = 9810
Therefore, the value for common factors is 9810.
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 = 132969868471800/(1x9810)
LCM = 132969868471800/9810
LCM = 13554522780
Thus, we can understand that the LCM of 785,860,327,654,921 is 13554522780.
