Given numbers are 830, 765, 622, 545

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 622 are 2 x 311

Prime factors of 545 are 5 x 109

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

Given numbers are 830, 765, 622, 545

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

Apply this formula for all numbers.

Step1:

LCM(830, 765) = 126990

GCD(830, 765) = ( 830 x 765 ) / 126990

= 830 / 765

= 830

Step2:

LCM(5, 622) = 3110

GCD(5, 622) = ( 5 x 622 ) / 3110

= 5 / 622

= 5

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 830, 765, 622, 545 is 1
