Question

is 1642060 a multiple of 7 or not answes

Answer 1

answer is no it is not multiple of 7

Answer 2

hey mate

to check a number whether it is divisible by 7 or not,we have two rules

rule 1: when the number is 2-digits

for example 84

we multiply the tenth digit by 3 and add the digit of unit place (which is here 4)

thus,8*3+4=28 which is divisible by 7 and hence 84 is also divisible by 7

rule 2:

when the number is more than 2 digits.

then we leave the two digits of right side of the number.
therefore
here we will take only 16420 and leave 60

we multiply this by 2 and then add it with 60

thus ,16420*2+60

=32840+60

=32900

same process continues

=329*2+00

=658

=6*2+58

=12+58

=70

hence the number 1642060 is divisible by 7
