Given numbers are 891, 135, 651, 666

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

Apply this formula for all numbers.

Step1:

LCM(891, 135) = 4455

GCD(891, 135) = ( 891 x 135 ) / 4455

= 891 / 135

= 891

Step2:

LCM(27, 651) = 5859

GCD(27, 651) = ( 27 x 651 ) / 5859

= 27 / 651

= 27

Step3:

LCM(3, 666) = 666

GCD(3, 666) = ( 3 x 666 ) / 666

= 3 / 666

= 3

So, Greatest Common Divisor of 891, 135, 651, 666 is 3
