Given numbers are 821, 415, 564

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

Apply this formula for all numbers.

Step1:

LCM(821, 415) = 340715

GCD(821, 415) = ( 821 x 415 ) / 340715

= 821 / 415

= 821

Step2:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

So, Greatest Common Divisor of 821, 415, 564 is 1
