Given numbers are 170, 970, 555, 221

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

Apply this formula for all numbers.

Step1:

LCM(170, 970) = 16490

GCD(170, 970) = ( 170 x 970 ) / 16490

= 170 / 970

= 170

Step2:

LCM(10, 555) = 1110

GCD(10, 555) = ( 10 x 555 ) / 1110

= 10 / 555

= 10

Step3:

LCM(5, 221) = 1105

GCD(5, 221) = ( 5 x 221 ) / 1105

= 5 / 221

= 5

So, Greatest Common Divisor of 170, 970, 555, 221 is 1
