Given numbers are 747, 993, 261, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 993) = 247257
GCD(747, 993) = ( 747 x 993 ) / 247257
= 747 / 993
= 747
Step2:
LCM(3, 261) = 261
GCD(3, 261) = ( 3 x 261 ) / 261
= 3 / 261
= 3
Step3:
LCM(3, 865) = 2595
GCD(3, 865) = ( 3 x 865 ) / 2595
= 3 / 865
= 3
So, Greatest Common Divisor of 747, 993, 261, 865 is 1
