What is the lcm of 74 and 104 ( I NEED A STEP BY STEP EXPLANATION ASAP)

74=2×37

104=2×2×2×13

L.C.M=common factor ×remaining factor

=2×2×2×37×13

=3848

11 feet 6 inches and 8 feet 6 inches

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
