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

Apply this formula for all numbers.

Step1:

LCM(666, 816) = 90576

GCD(666, 816) = ( 666 x 816 ) / 90576

= 666 / 816

= 666

Step2:

LCM(6, 402) = 402

GCD(6, 402) = ( 6 x 402 ) / 402

= 6 / 402

= 6

Step3:

LCM(6, 280) = 840

GCD(6, 280) = ( 6 x 280 ) / 840

= 6 / 280

= 6

So, Greatest Common Divisor of 666, 816, 402, 280 is 2
