LCM and HCF
What is the lcm and hcf of
10/21, 1/2, 5/7
Read Solution (Total 1)
-
- LCM in case of fraction = LCM of Numerator terms / HCF of Denominator terms
Similarly HCF in case of fraction = HCF of Numerator / LCM of Denominator terms
therefore LCM = LCM of (10,1,5) / HCF of (21,2,7)
= 10 / 1
=10
HCF = HCF of (10,1,5) / LCM of (21,2,7)
= 1 / 42
