Given numbers are 916, 222, 390, 491

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

Apply this formula for all numbers.

Step1:

LCM(916, 222) = 101676

GCD(916, 222) = ( 916 x 222 ) / 101676

= 916 / 222

= 916

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 491) = 982

GCD(2, 491) = ( 2 x 491 ) / 982

= 2 / 491

= 2

So, Greatest Common Divisor of 916, 222, 390, 491 is 1
