Sagot :
The least
common multiple of the given numbers
=> 55
=> 75
=> 115
First, let’s decompose or find the prime factors of each numbers
=> 55 = 5 x 11
=> 75 = 3 x 5 x 5 or 3 x 52
=> 115 = 5 x 23
Now, we have the common prime factor which is 5.
The uncommon prime factors which are 11, 3 and 23
And the greatest exponent = 52
LCM = 52 x 11 x 3 x 23
=> 18, 975
=> 55
=> 75
=> 115
First, let’s decompose or find the prime factors of each numbers

=> 115 = 5 x 23
Now, we have the common prime factor which is 5.
The uncommon prime factors which are 11, 3 and 23
And the greatest exponent = 52
LCM = 52 x 11 x 3 x 23
=> 18, 975
least common multiple of the given three numbers can be found out as follows
first have to divide all three numbers by factors that are common for all three
so first divide 55, 75 and 115 by 5
55/5 = 11
75/5 = 15
115/5 = 23
there are no common factors shared by 11, 15 and 23
so the factors are 5, 11 , 15 and 23
so to find the least common multiple
we have to find the products of the factors
5 x 11 x 15 x 23 = 18 975
least common multiple is 18 975
