Given numbers are 819, 147, 121, 315

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

Apply this formula for all numbers.

Step1:

LCM(819, 147) = 5733

GCD(819, 147) = ( 819 x 147 ) / 5733

= 819 / 147

= 819

Step2:

LCM(21, 121) = 2541

GCD(21, 121) = ( 21 x 121 ) / 2541

= 21 / 121

= 21

Step3:

LCM(1, 315) = 315

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

= 1 / 315

= 1

So, Greatest Common Divisor of 819, 147, 121, 315 is 1
