no, 6 does not divide evenly into 424 to give a whole number
The lowest number in the 21 times table and 24 times table is 21 x 24 21 24 --- 4 420 ----- 424
424 * 76 = 32,224
8 * 424 = 3,392
4 goes into 424, 106 times
Since 6 is a multiple of 3, all of the numbers in the 6 times table will be contained in the 3 times table.
They can only both be in the 1 times table as hcf(6, 79) = 1.
The Lowest Common Multiple of 2, 6 & 10 = 30 This is because 30 is in the 2 times table, 6 times table & 10 times table.
As one example: 8 times 53 = 424
It is: 76/424 times 100 = 18% rounded
