Given numbers are 128, 742, 861, 222

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 742 are 2 x 7 x 53

Prime factors of 861 are 3 x 7 x 41

Prime factors of 222 are 2 x 3 x 37

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

Given numbers are 128, 742, 861, 222

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

Apply this formula for all numbers.

Step1:

LCM(128, 742) = 47488

GCD(128, 742) = ( 128 x 742 ) / 47488

= 128 / 742

= 128

Step2:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

Step3:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

So, Greatest Common Divisor of 128, 742, 861, 222 is 1
