Question

Find the greatest number from which when 12 is
subtracted, the resulting number exactly divides the
numbers 336, 432, 528.

Answer 1

Answer:

60.

Step-by-step explanation:

First we find the highest common factor of the 3 nmbers:

336 = 2*2*2*2*3*7

432 = 2*2*2*2*3*3*3

528 = 2*2*2*2*3*11

So the HCF = 2*2*2*2*3 = 48

So the answer is 48 + 12 = 60.
