GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(867, 243) = 70227
GCD(867, 243) = ( 867 x 243 ) / 70227
= 867 / 243
= 867
Step2:
LCM(3, 921) = 921
GCD(3, 921) = ( 3 x 921 ) / 921
= 3 / 921
= 3
Step3:
LCM(3, 787) = 2361
GCD(3, 787) = ( 3 x 787 ) / 2361
= 3 / 787
= 3
So, Greatest Common Divisor of 867, 243, 921, 787 is 1
