Answer 1

210

Explanation:

so the four Smallest Primes :

2, 3, 5, 7

When the number is Divided by 2, 3, 5 & 7 Leaves remainder 1

so N = 2a + 1

N = 3b + 1

N = 5c + 1

N = 7d + 1

-> N - 1 = 2a = 3b = 5c = 7d

N - 1 = 2 * 3 * 5 * 7

-> N - 1 = 210

-> N = 211

Next N - 1 = 2(210)

-> N - 1 = 420

-> N =421

Difference = 421 - 211 = 210
