8 is the answer. Because 4x8=32 which means it is not the lowest, since 4 is a multiple of 8, 8 is the least common denominator. thats why its called least because it is the lowest possible value that both fractions could have as denominators for making them similar fractions.

Yikes, what contradicting answers!
The lowest common denominator or least common denominator (LCD) is the least common multiple of the denominators of a set of fractions.
The least common multiple or lowest common multiple (LCM) or smallest common multiple of two integers a and b is the smallest positive integer that is a multiple of both a and b.
knowing that:
3/4 and 4/8
4 and 8 are the denominators
They are both multiples of 2 and 4 (4 = 4*1 = 2*2 and 8 = 4*2 = 2*4 = 2*2*2)
But, we have to choose "4" because the 3 (in 3/4) can not be reduced down further without getting a fraction.
So you end up having 3/4 and 2/4
Hope that helps

3/4 is the lowest common denominator of 3/4.
The lowest common denominator of 4/8 is 1/2.

Because 4 and 8 have common factor which 8.
4 = 2x2
8 = 2x2x2
Here common factors are 2,2,2=8 because
4 = {2}are same x [2] are same
8 = {2} x [2] x (2) left over

Because 8 is divisible by 4. If the higher denominator is ever divisible by the lower, you can just use the higher. So in this case, 8 is the lcd

the lowest is eight because 4 and 8 both go into it
4 *2=8
8*1=8
