Question

Find the HCF :-
219,1102,1218

Answer 1

Answer:

1

Step-by-step explanation:

First prime factorise 219, 1102, 1218.

Prime factorisation of 219.

Prime factorisation of 1102.

Prime factorisation of 1218.

We know that.

HCF (219, 1102, 1218) = 1.

Answer 2

Answer :-

HCF (219, 1102, 1218) = 1

Solution :-

First prime factorise 219, 1102, 1218

Prime factorisation of 219

Prime factorisation of 1102

Prime factorisation of 1218

219 = 3 * 73 * 1

1102 = 2 * 19 * 29 * 1

1218 = 2 * 3 * 7 * 29 * 1

We know that

HCF = Product the smallest power of each common prime factor of the numbers.

But here we dont have any common prime factor.

So 219, 1102, 1218 are co - primes

HCF of any co - primes is 1

HCF (219, 1102, 1218) = 1
