Question

92,128 find the LCM using prime factorisation​

Answer 1

Answer:

factors of 128 = 2, 4, 8, 16, 32, 64, 128 divided by 2, 2, 2, 2, 2, 2, 2, gives no remainder. They are integers and prime numbers of 128, they are also called composite number.                                                                                                    92 = 1 x 92, 2 x 46, or 4 x 23. Factors of 92: 1, 2, 4, 23, 46, 92. Prime factorization: 92 = 2 x 2 x 23 which can also be written 92 = 2² x 23

Answer 2

Answer:

LCM of the given number will be 2944

Step-by-step explanation:

In context to question asked,

We have to determine the LCM

As per question,

We have,

92, 128

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,

$92 = 2 \times 2 \times 23\\128 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times2\\=>LCM = 2\times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 23\\=>128 \times 23\\=>2944$
