Answer:
30
Explanation:
To find the Lowest Common Multiple(LCM), factor out each number.
2x13, 3x13, 2x5x13 Now take all the non-repeating terms and multiply them together.
2x3x5x13=390
To find the Highest Common Factor(HCF), multiply all the common factors together.
The only common factor in all 2x13, 3x13, 2x5x13 is 13, so the HCF is 13.
We have to find LCM/HCF and since LCM=390, and HCF=13 the expression is 390/13.
390/13=30
