Given numbers are 128, 875, 72, 530

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

Apply this formula for all numbers.

Step1:

LCM(128, 875) = 112000

GCD(128, 875) = ( 128 x 875 ) / 112000

= 128 / 875

= 128

Step2:

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

= 1 / 72

= 1

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 128, 875, 72, 530 is 1
