Given numbers are 666, 640, 891, 766

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

Apply this formula for all numbers.

Step1:

LCM(666, 640) = 213120

GCD(666, 640) = ( 666 x 640 ) / 213120

= 666 / 640

= 666

Step2:

LCM(2, 891) = 1782

GCD(2, 891) = ( 2 x 891 ) / 1782

= 2 / 891

= 2

Step3:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

So, Greatest Common Divisor of 666, 640, 891, 766 is 1
