Given numbers are 861, 644, 84, 481

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

Apply this formula for all numbers.

Step1:

LCM(861, 644) = 79212

GCD(861, 644) = ( 861 x 644 ) / 79212

= 861 / 644

= 861

Step2:

LCM(7, 84) = 84

GCD(7, 84) = ( 7 x 84 ) / 84

= 7 / 84

= 7

Step3:

LCM(7, 481) = 3367

GCD(7, 481) = ( 7 x 481 ) / 3367

= 7 / 481

= 7

So, Greatest Common Divisor of 861, 644, 84, 481 is 1
