Answer :
Final answer:
The H.C.F of numbers 660 and 2100, given their LCM is 23100, is 60, which does not match any of the provided options (110, 220, 330, 440). This was found by dividing the product of the two numbers by their given LCM.
Explanation:
The subject of this question is Mathematics, specifically the topic of finding the Highest Common Factor (H.C.F.) between two numbers, given their Lowest Common Multiple (LCM). The numbers here are 660 and 2100, and their LCM is given as 23100.
In order to find the H.C.F., you need to know the relationship that connects two numbers, their LCM, and their H.C.F., which is that the product of the two numbers is equal to the product of their H.C.F. and LCM. This means that if you find the product of the two numbers (660 and 2100) and divide it by their LCM (23100), you'll get their H.C.F.
660 * 2100 / 23100 equals 60. Therefore, none of the options provided (110, 220, 330, 440) are correct.
