GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(324, 789) = 85212
GCD(324, 789) = ( 324 x 789 ) / 85212
= 324 / 789
= 324
Step2:
LCM(3, 117) = 117
GCD(3, 117) = ( 3 x 117 ) / 117
= 3 / 117
= 3
Step3:
LCM(3, 253) = 759
GCD(3, 253) = ( 3 x 253 ) / 759
= 3 / 253
= 3
So, Greatest Common Divisor of 324, 789, 117, 253 is 1
