Answer:
H.C.F. of 1197, 5320 and 4389 = 133
Step-by-step explanation:
The number whose H.C.F. we need to find are given to be : 1197, 5320, 4389
The H.C.F. is to find out by using prime factorization, So finding the prime factors of the given three numbers
1197 = 3 × 3 × 7 × 19
5320 = 2 × 2 × 2 × 5 × 7 × 19
4389 = 3 × 7 × 11 × 19
Now, To find the H.C.F. find the common factors in all the three numbers
So, Common Factors = 7 and 19
Hence, H.C.F. of 1197, 5320 and 4389 = 7 × 19
= 133
