Given numbers are 921, 219, 661, 916

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

Apply this formula for all numbers.

Step1:

LCM(921, 219) = 67233

GCD(921, 219) = ( 921 x 219 ) / 67233

= 921 / 219

= 921

Step2:

LCM(3, 661) = 1983

GCD(3, 661) = ( 3 x 661 ) / 1983

= 3 / 661

= 3

Step3:

LCM(1, 916) = 916

GCD(1, 916) = ( 1 x 916 ) / 916

= 1 / 916

= 1

So, Greatest Common Divisor of 921, 219, 661, 916 is 1
