If you take the units digit and double it then subtract it from the rest of the number then the difference is divisible by seven. You may have to do it several times.
574
57-8=49
So it is a multiple of 7.
For each multiple add 7. For example 12*7= 84 therefore 13*7= 91 (84+7)
4- last two digits are a multiple of 4 7-take the last digit and subtract it from the rest of the number and if multiple of 7 (including 0) 8- last three digits are multiple of 8
I assume you mean "divisibility rule". Separate the last three digits, and subtract it from the remaining digits. For example: 45003: separate 45 and 003, and subtract 45 - 3 = 42. Since 42 is a multiple of 7, the original number is a multiple of seven. Note that this rule works for 7, 11, and 13. The reason it works is related to the fact that 1001 = 7 x 11 x 13.
9th multiple of 7
There is no such number. Since if x were the largest multiple of 3 and 7 then what about 2x? 2x would be a multiple of 3 since x is a multiple of 3; 2x would be a multiple of 7 since x is a multiple of 7; and 2x is bigger than x. So x cannot be the largest.

Double the last digit. Subtract it from the rest. If the result is divisible by 7, the original number is divisible by 7.

The smallest multiple of 7 is 7.
The multiple for 6 are 2 times 4
No, it is not a multiple of 7.
well,1 and 5 or 7 is the multiple of 5 and 7
No, 24 is not a multiple of 7. 7 does not divide equally into it.
Substratum rule is when there are multiple facets of layers for the rule of whatever is being governed or managed.
