Question

82,102 find the LCM using prime factorisation​

Answer 1

Lcm of 82 and102 is 2×41×51

Answer 2

Answer:

LCM of the given number will be 4182

Step-by-step explanation:

In context to question asked,

We have to determine the LCM

As per question,

We have,

82 , 102

As it is mentioned to determine the LCM by using prime factorisation method.

We know that,

• LCM of two or more number is that particular number which is the smallest common multiple of all the given number.

• Prime factorisation method is the method in which we convert the given number as a factors of prime numbers.

• Prime numbers are those numbers which are either divisible by 1 or itself.

So, converting the given number in form of prime numbers,

We will get,

$82 = 2 \times 41\\102 = 51 \times 2\\LCM = 2 \times 51 \times 41 = 102 \times 41 = 4182$
