Given numbers are 653, 728, 163, 878

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

Apply this formula for all numbers.

Step1:

LCM(653, 728) = 475384

GCD(653, 728) = ( 653 x 728 ) / 475384

= 653 / 728

= 653

Step2:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 653, 728, 163, 878 is 1
