. Write down a program that will find Greatest Common Factor (GCF) of THREEintegers a, b, and c given as input. For example if a = 24, b = 54, and c = 30 then youroutput will be 6 because the factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24; the factors of 54 are 1,2, 3, 6, 9, 18, 27, 54; and the factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30. Among those factors1, 2, 3 and 6 are common factors and 6 is the greatest common factor.
