GCD of numbers is the greatest common divisor

So, the GCD (83, 61, 75, 30) = 1.

Given numbers are 83, 61, 75, 30

The list of prime factors of all numbers are

Prime factors of 83 are 83

Prime factors of 61 are 61

Prime factors of 75 are 3 x 5 x 5

Prime factors of 30 are 2 x 3 x 5

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

Given numbers are 83, 61, 75, 30

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

Apply this formula for all numbers.

Step1:

LCM(83, 61) = 5063

GCD(83, 61) = ( 83 x 61 ) / 5063

= 83 / 61

= 83

Step2:

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

= 1 / 75

= 1

Step3:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

So, Greatest Common Divisor of 83, 61, 75, 30 is 1
