Given numbers are 611,819,403,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,819,403,392 is 66823848.
Find LCM of 611,819,403,392 with Prime Factorization
| 7 | 611, 819, 403, 392 |
| 13 | 611, 117, 403, 56 |
| 47, 9, 31, 56 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 47 x 9 x 31 x 56 = 66823848
Therefore, the lowest common multiple of 611,819,403,392 is 66823848.
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.
611 x 819 x 403 x 392 = 79052612184
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.
611 : 1, 13, 47, 611
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
403 : 1, 13, 31, 403
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,819,403,392, is 1.
Now, the common factors can be found like this.
611:13x 47
819:3x 3x 7x 13
403:13x 31
392:2x 2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 13 = 1183
Therefore, the value for common factors is 1183.
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 = 79052612184/(1x1183)
LCM = 79052612184/1183
LCM = 66823848
Thus, we can understand that the LCM of 611,819,403,392 is 66823848.
