CRT - 100 = 4 * 25 15 * 37 * 63 * 51 * 97 * 17 mod 4 = -1 = 3 15 * 37 * 63 * 51 * 97 * 17 mod 25 5 is common factor here 3 * 37 * 63 * 51 * 97 * 17 mod 5=-2 * 2 * 3 * 1 * 2 * 2 = 2 so remainder =10 so 25a + 10 = 4b + 3 35

a x b = HCF (a, b) x LCM (a, b)

If a and b are co primes then HCF (a, b) = 1So for co prime numbers, a x b = LCM (a, b)

Q45) Find the largest value of a for which 100 + a^3 becomes perfectly divisible by 10 + a

awesome work sir......

@Rohit-Rathore HCF of 8 and 27 is not 12.
