Given numbers are 402, 813, 863, 315

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

Apply this formula for all numbers.

Step1:

LCM(402, 813) = 108942

GCD(402, 813) = ( 402 x 813 ) / 108942

= 402 / 813

= 402

Step2:

LCM(3, 863) = 2589

GCD(3, 863) = ( 3 x 863 ) / 2589

= 3 / 863

= 3

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 402, 813, 863, 315 is 1
