Given numbers are 564, 972, 690, 389

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

Apply this formula for all numbers.

Step1:

LCM(564, 972) = 45684

GCD(564, 972) = ( 564 x 972 ) / 45684

= 564 / 972

= 564

Step2:

LCM(12, 690) = 1380

GCD(12, 690) = ( 12 x 690 ) / 1380

= 12 / 690

= 12

Step3:

LCM(6, 389) = 2334

GCD(6, 389) = ( 6 x 389 ) / 2334

= 6 / 389

= 6

So, Greatest Common Divisor of 564, 972, 690, 389 is 1
