Given numbers are 981, 566, 636, 100

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 566 are 2 x 283

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 100 are 2 x 2 x 5 x 5

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

Given numbers are 981, 566, 636, 100

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

Apply this formula for all numbers.

Step1:

LCM(981, 566) = 555246

GCD(981, 566) = ( 981 x 566 ) / 555246

= 981 / 566

= 981

Step2:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

Step3:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

So, Greatest Common Divisor of 981, 566, 636, 100 is 1
