Answer:
the question you have asked it's about the core prime so firstly you have to fully understand the CO primes the CO primes are the numbers which divided only by itself or by 1
Step-by-step explanation:
1 - as you have asked in the first portion 161 and 192
as you can see here 161 in this the last number in the ones at the ones place there is one through which we can generally understand that it can be divisible by 3 7 or 1 so now you
have to solve it by taking the division portion buy 3 or 7 ,1
2 - 72 and 1440 in this question you can see here that N72 at once place there is two true you can see that 2 is a prime number or we can say that it's a core prime as it is only divisible by its or by one , 1440 you can see here that at once place there is 0 as you know about the core prime that 0 is not a coprime so it can generally taken as not
3- 680 and 960 as you can see here in 680 in the last digit ones there is zero as I have told that zero is a not a prime or not a prime it we can only divisible by 5 so in another question 960 there is also zero is at their position so you have to check it it is the prime or coprime
beta aapane Jo question poochha hai ki coprime aur prime kya hote Hain to main aapko yah pata hona chahie ki coprime aur prime kya hota hai agar aapko coprime samajh mein a jaega to aapko yah question bahut aaram se kar lenge aap lekin agar nahin Sun jaega to aapko aane Wale 6,7,8 mein bahut problem hogi in questions kyunki sab questions ke base per hi hote hain so be careful to your classes
