which is the largest 3 digit number axactly divisible by 8,12,16,18?
Answers
★ Given ★
Three numbers 8,10 and 12
★ Find out ★
We need to find out the largest 3-digit number which is exactly divisible by 8, 10 and 12
★ Solution ★
To find out the largest 3-digit number which is exactly divisible by 8, 10 and 12
first let us calculate the L.C.M 8, 10 and 12
L.C.M of 8, 10, 12 = 2 x 2 x 2 x 3 x 5
Hence, LCM of 8, 10, 12 = 120
We have to find the greatest 3 digit multiple of 120
Therefore, the number is
120 x 8 = 960
120 x 10 = 1200
120 x 12 = 1440
The 1200 and 1440 are not 3-digit numbers.
Hence, the greatest 3- digit number exactly divisible by 8, 10 & 12 is 960.
★ Verification ★
Now, let us check whether 960 is divisible by 8, 10 and 12.
960 ÷ 8 = 120
960 ÷ 10 = 96
960 ÷ 12 = 80
So the greatest 3-digit number is 960.
