GCD of numbers is the greatest common divisor

So, the GCD (63, 38, 85, 61) = 1.

Given numbers are 63, 38, 85, 61

The list of prime factors of all numbers are

Prime factors of 63 are 3 x 3 x 7

Prime factors of 38 are 2 x 19

Prime factors of 85 are 5 x 17

Prime factors of 61 are 61

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 63, 38, 85, 61

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(63, 38) = 2394

GCD(63, 38) = ( 63 x 38 ) / 2394

= 63 / 38

= 63

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

Step3:

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

= 1 / 61

= 1

So, Greatest Common Divisor of 63, 38, 85, 61 is 1
