Given numbers are 208, 666, 401, 387

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

Apply this formula for all numbers.

Step1:

LCM(208, 666) = 69264

GCD(208, 666) = ( 208 x 666 ) / 69264

= 208 / 666

= 208

Step2:

LCM(2, 401) = 802

GCD(2, 401) = ( 2 x 401 ) / 802

= 2 / 401

= 2

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 208, 666, 401, 387 is 1
