Given numbers are 618, 821, 170

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

Apply this formula for all numbers.

Step1:

LCM(618, 821) = 507378

GCD(618, 821) = ( 618 x 821 ) / 507378

= 618 / 821

= 618

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 618, 821, 170 is 1
