3[201 The greatest common divisor is the largest positive integer that divides the numbers without a remainder. For example, the GCD of 8 and 12 is 4. Use the MATLAB Help Window to find a MATLAB built-in function that determines the greatest common divisor of two numbers. Then use the function to show that the greatest common divisor of: (a) 91 and 147 is 7. (b) 555 and 962 is 37
