What number is divisible by 7 and 9 and in between 200 and 300?
First, compute the least common multiple of 7 and 9. lcm(7,9) = (7*9)/gcd(7,9) where gcd(7,9) is the greatest, common divisor of 7 and 9, that is the largest number that divides both numbers. In this case, the gcd is 1. So, lcm(7,9)=7*9=63 So we want to find a multiple of 63 between 200 and 300 Note that 63 < 300-200 = 100. So we must be able to find a number in between 200 and 300 that is a multiple of 63. Now we divide 200 by 63 to get 3.174603.... Since 200/63 = 3.174603 < 4 (rounding up to the nearest integer) It follows that 200/63 < 4 and then 200 < 63*4 Since 7, and 9 both divide 63, it follows they both divide 63*4 So the answer is: 252
What times 4 equals 63?
63/4 or 15.75 4 * x = 63 where x is our unknown number x = 63/4 dividing both sides by 4 4 * 63/4 = 63 as the 4's cancel
