Given numbers are 545, 561, 632, 988

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 561 are 3 x 11 x 17

Prime factors of 632 are 2 x 2 x 2 x 79

Prime factors of 988 are 2 x 2 x 13 x 19

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

Given numbers are 545, 561, 632, 988

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

Apply this formula for all numbers.

Step1:

LCM(545, 561) = 305745

GCD(545, 561) = ( 545 x 561 ) / 305745

= 545 / 561

= 545

Step2:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

Step3:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

So, Greatest Common Divisor of 545, 561, 632, 988 is 1
