Given numbers are 691,793,286,272
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,793,286,272 is 1639505296.
Find LCM of 691,793,286,272 with Prime Factorization
2 | 691, 793, 286, 272 |
13 | 691, 793, 143, 136 |
691, 61, 11, 136 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 691 x 61 x 11 x 136 = 1639505296
Therefore, the lowest common multiple of 691,793,286,272 is 1639505296.
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.
691 x 793 x 286 x 272 = 42627137696
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.
691 : 1, 691
793 : 1, 13, 61, 793
286 : 1, 2, 11, 13, 22, 26, 143, 286
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,793,286,272, is 1.
Now, the common factors can be found like this.
691:691
793:13x 61
286:2x 11x 13
272:2x 2x 2x 2x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 42627137696/(1x26)
LCM = 42627137696/26
LCM = 1639505296
Thus, we can understand that the LCM of 691,793,286,272 is 1639505296.
