Given numbers are 882, 644, 21, 547

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

Apply this formula for all numbers.

Step1:

LCM(882, 644) = 40572

GCD(882, 644) = ( 882 x 644 ) / 40572

= 882 / 644

= 882

Step2:

LCM(14, 21) = 42

GCD(14, 21) = ( 14 x 21 ) / 42

= 14 / 21

= 14

Step3:

LCM(7, 547) = 3829

GCD(7, 547) = ( 7 x 547 ) / 3829

= 7 / 547

= 7

So, Greatest Common Divisor of 882, 644, 21, 547 is 1
