Given numbers are 217, 645, 453, 276

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

Apply this formula for all numbers.

Step1:

LCM(217, 645) = 139965

GCD(217, 645) = ( 217 x 645 ) / 139965

= 217 / 645

= 217

Step2:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

Step3:

LCM(1, 276) = 276

GCD(1, 276) = ( 1 x 276 ) / 276

= 1 / 276

= 1

So, Greatest Common Divisor of 217, 645, 453, 276 is 1
