Given numbers are 865, 671, 218, 453

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

Apply this formula for all numbers.

Step1:

LCM(865, 671) = 580415

GCD(865, 671) = ( 865 x 671 ) / 580415

= 865 / 671

= 865

Step2:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

Step3:

LCM(1, 453) = 453

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

= 1 / 453

= 1

So, Greatest Common Divisor of 865, 671, 218, 453 is 1
