The LCM of 818,549,905,774,971 is 16969221275130.
Find LCM of 818,549,905,774,971 with Prime Factorization
| 2 | 818, 549, 905, 774, 971 |
| 3 | 409, 549, 905, 387, 971 |
| 3 | 409, 183, 905, 129, 971 |
| 409, 61, 905, 43, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 409 x 61 x 905 x 43 x 971 = 16969221275130
Therefore, the lowest common multiple of 818,549,905,774,971 is 16969221275130.
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.
818 x 549 x 905 x 774 x 971 = 305445982952340
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.
818 : 1, 2, 409, 818
549 : 1, 3, 9, 61, 183, 549
905 : 1, 5, 181, 905
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,549,905,774,971, is 1.
Now, the common factors can be found like this.
818:2x 409
549:3x 3x 61
905:5x 181
774:2x 3x 3x 43
971:971
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 3 = 18
Therefore, the value for common factors is 18.
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 = 305445982952340/(1x18)
LCM = 305445982952340/18
LCM = 16969221275130
Thus, we can understand that the LCM of 818,549,905,774,971 is 16969221275130.
