Given numbers are 850,969,849,646,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,969,849,646,931 is 671856150.
Find LCM of 850,969,849,646,931 with Prime Factorization
| 2 | 850, 969, 849, 646, 931 |
| 3 | 425, 969, 849, 323, 931 |
| 17 | 425, 323, 283, 323, 931 |
| 19 | 25, 19, 283, 19, 931 |
| 25, 1, 283, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 25 x 1 x 283 x 1 x 49 = 671856150
Therefore, the lowest common multiple of 850,969,849,646,931 is 671856150.
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.
850 x 969 x 849 x 646 x 931 = 420564481640100
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
969 : 1, 3, 17, 19, 51, 57, 323, 969
849 : 1, 3, 283, 849
646 : 1, 2, 17, 19, 34, 38, 323, 646
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,969,849,646,931, is 1.
Now, the common factors can be found like this.
850:2x 5x 5x 17
969:3x 17x 19
849:3x 283
646:2x 17x 19
931:7x 7x 19
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 17x 17x 19x 19 = 625974
Therefore, the value for common factors is 625974.
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 = 420564481640100/(1x625974)
LCM = 420564481640100/625974
LCM = 671856150
Thus, we can understand that the LCM of 850,969,849,646,931 is 671856150.
