Given numbers are 170, 821, 530

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

Apply this formula for all numbers.

Step1:

LCM(170, 821) = 139570

GCD(170, 821) = ( 170 x 821 ) / 139570

= 170 / 821

= 170

Step2:

LCM(1, 530) = 530

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

= 1 / 530

= 1

So, Greatest Common Divisor of 170, 821, 530 is 1
