Given numbers are 137,548,138,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,548,138,557 is 21061284.
Find LCM of 137,548,138,557 with Prime Factorization
| 2 | 137, 548, 138, 557 |
| 137 | 137, 274, 69, 557 |
| 1, 2, 69, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 137 x 1 x 2 x 69 x 557 = 21061284
Therefore, the lowest common multiple of 137,548,138,557 is 21061284.
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.
137 x 548 x 138 x 557 = 5770791816
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.
137 : 1, 137
548 : 1, 2, 4, 137, 274, 548
138 : 1, 2, 3, 6, 23, 46, 69, 138
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,548,138,557, is 1.
Now, the common factors can be found like this.
137:137
548:2x 2x 137
138:2x 3x 23
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 137 = 274
Therefore, the value for common factors is 274.
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 = 5770791816/(1x274)
LCM = 5770791816/274
LCM = 21061284
Thus, we can understand that the LCM of 137,548,138,557 is 21061284.
