The correct option is A Factors of number≤number≤Multiple of number
If a number is a factor of a big number, then that big number is a multiple of the first number.
Example: Take a number 6
6×1=66×2=126×3=18 . . .6×10=60
Here, 6,12,18....60,.. are multiples of 6.
6=2×36=6×1
Here, 1,2,3 & 6 are factors of 6.
Hence Factors of number≤number≤Multiple of number
