Given numbers are 243, 315, 142, 958

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

Apply this formula for all numbers.

Step1:

LCM(243, 315) = 8505

GCD(243, 315) = ( 243 x 315 ) / 8505

= 243 / 315

= 243

Step2:

LCM(9, 142) = 1278

GCD(9, 142) = ( 9 x 142 ) / 1278

= 9 / 142

= 9

Step3:

LCM(1, 958) = 958

GCD(1, 958) = ( 1 x 958 ) / 958

= 1 / 958

= 1

So, Greatest Common Divisor of 243, 315, 142, 958 is 1
