HCF of 408 and 1032 Solved Example
Question: If HCF = 24 and product of two numbers = 421056, find the LCM.
Solution:
Given
HCF = 24
Product = 421056
We know that
HCF × LCM = Product
LCM = Product/HCF
LCM = 421056/24
LCM = 17544
Hence, the LCM is 17544.
Frequently Asked Questions on HCF of 408 and 1032
What is the HCF of 408 and 1032?
How can we find the HCF of 408 and 1032 using the long division method?
Which methods can be used to find the HCF of 408 and 1032?
If LCM = 17544 and HCF = 24 for two numbers, determine the other number when one number is 1032.
Consider y as the other number
Given LCM = 17544 and HCF = 24
HCF × LCM = 1032 × y
y = (HCF × LCM)/ 1032
y = (24 × 17544)/ 1032
y = 408
Therefore, the other number is 408.
