What is the get for 42 63 and 84?
The greatest common divisor (GCD) of 42, 63, and 84 is 21. This is determined by finding the largest number that divides all three numbers without leaving a remainder. The prime factorizations of the numbers are 2 × 3 × 7 (42), 3² × 7 (63), and 2² × 3 × 7 (84). The common factors are 3 and 7, and their product (3 × 7) gives the GCD of 21.
