Given numbers are 847,869,839,370,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,869,839,370,860 is 1786375022740.
Find LCM of 847,869,839,370,860 with Prime Factorization
| 2 | 847, 869, 839, 370, 860 |
| 5 | 847, 869, 839, 185, 430 |
| 11 | 847, 869, 839, 37, 86 |
| 77, 79, 839, 37, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 77 x 79 x 839 x 37 x 86 = 1786375022740
Therefore, the lowest common multiple of 847,869,839,370,860 is 1786375022740.
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 869 x 839 x 370 x 860 = 196501252501400
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
869 : 1, 11, 79, 869
839 : 1, 839
370 : 1, 2, 5, 10, 37, 74, 185, 370
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,869,839,370,860, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
869:11x 79
839:839
370:2x 5x 37
860:2x 2x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 196501252501400/(1x110)
LCM = 196501252501400/110
LCM = 1786375022740
Thus, we can understand that the LCM of 847,869,839,370,860 is 1786375022740.
