Given numbers are 654, 861, 613, 284

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

Apply this formula for all numbers.

Step1:

LCM(654, 861) = 187698

GCD(654, 861) = ( 654 x 861 ) / 187698

= 654 / 861

= 654

Step2:

LCM(3, 613) = 1839

GCD(3, 613) = ( 3 x 613 ) / 1839

= 3 / 613

= 3

Step3:

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

= 1 / 284

= 1

So, Greatest Common Divisor of 654, 861, 613, 284 is 1
