Given numbers are 247, 276, 657, 411

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

Apply this formula for all numbers.

Step1:

LCM(247, 276) = 68172

GCD(247, 276) = ( 247 x 276 ) / 68172

= 247 / 276

= 247

Step2:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 247, 276, 657, 411 is 1
