Yes, what is the lowest common multiple (LCM) of 30 and 39?
30=2*3*5
39=3*13
The LCM is the product of the highest power of each of the prime factors, namely
LCM=2*3*5*13=390
No. of packs required = 390/39=10
30=2*3*5
39=3*13
The LCM is the product of the highest power of each of the prime factors, namely
LCM=2*3*5*13=390
No. of packs required = 390/39=10
