30 goes into it 152 times. Like 152 goes into it 30 times.
multiply the denominators
Answer: 30 If those numbers are denominators, the least common denominator is the least common multiple of the three. In this case, 30 is the LCM of 6, 10 and 15, so 30 is the least common denominator.
6 2x3x5=30 30 / 2 =15 30/3=10 30/5 =6
You use them when there are 2 fractions with different denominators.
