GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 558) = 15066
GCD(243, 558) = ( 243 x 558 ) / 15066
= 243 / 558
= 243
Step2:
LCM(9, 316) = 2844
GCD(9, 316) = ( 9 x 316 ) / 2844
= 9 / 316
= 9
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 243, 558, 316, 921 is 1
