How-to: What is the LCM of 160 and 175?
The below solved example with step by step work shows how to find what is the lcm of 160 and 175 by using prime factors method and division method.
Solved example using prime factors method:
What is the LCM of 160 and 175?
step 1
Address the input parameters, values and observe what to be found:
Input parameters and values:
A = 160
B = 175
What to be found:
find the lcm of 160 and 175
step 2 Find the prime factors of 160 and 175:
Prime factors of 160 = 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 175 = 5 x 5 x 7

{5} is the most repeated factor and {2 x 2 x 2 x 2 x 2 x 5 x 7} are the non-repeated factors of 160 and 175.
step 4 Find the product of repeated and non-repeated prime factors of 160 and 175:
= 5 x 2 x 2 x 2 x 2 x 2 x 5 x 7
= 5600
lcm(160 and 175) = 5600
Hence,
lcm of 160 and 175 is 5600
This special division method is one of the easiest ways to understand the entire calculation to find the LCM of 160 and 175.
step 1 Address the input parameters, values and observe what to be found:
Input parameters and values:
Integers: 160 and 175
What to be found:
lcm (160, 175) = ?
step 2 Arrange the given integers in the horizontal form with space or comma separated format:
160 and 175
step 3 Choose the divisor which divides each or most of the given integers (160 and 175), divide each integers separately and write down the quotient in the next line right under the respective integers.
