Given numbers are 253,781,161,256
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,781,161,256 is 32189696.
Find LCM of 253,781,161,256 with Prime Factorization
11 | 253, 781, 161, 256 |
23 | 23, 71, 161, 256 |
1, 71, 7, 256 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 1 x 71 x 7 x 256 = 32189696
Therefore, the lowest common multiple of 253,781,161,256 is 32189696.
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.
253 x 781 x 161 x 256 = 8143993088
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.
253 : 1, 11, 23, 253
781 : 1, 11, 71, 781
161 : 1, 7, 23, 161
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,781,161,256, is 1.
Now, the common factors can be found like this.
253:11x 23
781:11x 71
161:7x 23
256:2x 2x 2x 2x 2x 2x 2x 2
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23 = 253
Therefore, the value for common factors is 253.
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 = 8143993088/(1x253)
LCM = 8143993088/253
LCM = 32189696
Thus, we can understand that the LCM of 253,781,161,256 is 32189696.
