Given numbers are 628,187,471,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,187,471,181 is 63767748.
Find LCM of 628,187,471,181 with Prime Factorization
157 | 628, 187, 471, 181 |
4, 187, 3, 181 |
Multiply the prime numbers at the bottom and the left side.
157 x 4 x 187 x 3 x 181 = 63767748
Therefore, the lowest common multiple of 628,187,471,181 is 63767748.
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.
628 x 187 x 471 x 181 = 10011536436
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.
628 : 1, 2, 4, 157, 314, 628
187 : 1, 11, 17, 187
471 : 1, 3, 157, 471
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,187,471,181, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
187:11x 17
471:3x 157
181:181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
157 = 157
Therefore, the value for common factors is 157.
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 = 10011536436/(1x157)
LCM = 10011536436/157
LCM = 63767748
Thus, we can understand that the LCM of 628,187,471,181 is 63767748.
