Answer and Explanations

Amit Sahu

Solution is 2,3,5,11

2970 = 2 * 5 * 3 * 3 * 11

30 = 2*3*5

LCM of the two numbers  = 2*3*3*3*5*11 = 2970

So the prime factors are = 2,3,5,11

Ritesh Phogat

It's Simple

Factors of [2970] = 2*3*5*3*3*11

Factors of [30] =     2*3*5HCF = 2*3*5 = 30

LCM = 2*3*5*32*11 = 30*99 = 2970

It's Simple

Factors of [2970] = 2*3*5*3*3*11

Factors of [30] =     2*3*5

HCF = 2*3*5* 

LCM = 2*3*5*3*3*11 = 30*99 =2970

Okay i know LCM and HCF but what are Prime Factors
Amit
Prime factors are numbers which are only divisible by 1 and number itself for e.g
let's take and example 2
2 is prime number as it has 2 factors 1 and 2

But 4 isn't a prime number as it has 1,2,4 , it has 3 factors so it isn't a prime number
