Given numbers are 921, 441, 78, 411

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

Apply this formula for all numbers.

Step1:

LCM(921, 441) = 135387

GCD(921, 441) = ( 921 x 441 ) / 135387

= 921 / 441

= 921

Step2:

LCM(3, 78) = 78

GCD(3, 78) = ( 3 x 78 ) / 78

= 3 / 78

= 3

Step3:

LCM(3, 411) = 411

GCD(3, 411) = ( 3 x 411 ) / 411

= 3 / 411

= 3

So, Greatest Common Divisor of 921, 441, 78, 411 is 3
