GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 102) = 8262
GCD(243, 102) = ( 243 x 102 ) / 8262
= 243 / 102
= 243
Step2:
LCM(3, 957) = 957
GCD(3, 957) = ( 3 x 957 ) / 957
= 3 / 957
= 3
Step3:
LCM(3, 543) = 543
GCD(3, 543) = ( 3 x 543 ) / 543
= 3 / 543
= 3
So, Greatest Common Divisor of 243, 102, 957, 543 is 3
