Given numbers are 391,128,191,955
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,128,191,955 is 47795840.
Find LCM of 391,128,191,955 with Prime Factorization
191 | 391, 128, 191, 955 |
391, 128, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
191 x 391 x 128 x 1 x 5 = 47795840
Therefore, the lowest common multiple of 391,128,191,955 is 47795840.
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.
391 x 128 x 191 x 955 = 9129005440
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.
391 : 1, 17, 23, 391
128 : 1, 2, 4, 8, 16, 32, 64, 128
191 : 1, 191
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,128,191,955, is 1.
Now, the common factors can be found like this.
391:17x 23
128:2x 2x 2x 2x 2x 2x 2
191:191
955:5x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
191 = 191
Therefore, the value for common factors is 191.
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 = 9129005440/(1x191)
LCM = 9129005440/191
LCM = 47795840
Thus, we can understand that the LCM of 391,128,191,955 is 47795840.
