Frequently Asked Questions on LCM of 14 and 91
Find the GCF if the LCM of 14 and 91 is 182.
We know that
LCM x GCF = 14 x 91
As LCM (14, 91) is 182
182 x GCF = 1274
GCF = 1274/182 = 7
Determine the LCM of 14 and 91.
Show the relation between GCF and LCM of 14 and 91.
The relation between GCF and LCM of 14 and 91 is:
LCM x GCF = 14 x 91
LCM x GCF = 1274
The LCM and GCD of two numbers are 182 and 7. If 14 is one number, find the other.
Consider the other number as y
GCD x LCM = 14 x y
y = (GCD x LCM)/14
y = (7 x 182)/14
y = 91
Hence, the other number is 91.
