Given numbers are 735, 780, 871, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(735, 780) = 38220
GCD(735, 780) = ( 735 x 780 ) / 38220
= 735 / 780
= 735
Step2:
LCM(15, 871) = 13065
GCD(15, 871) = ( 15 x 871 ) / 13065
= 15 / 871
= 15
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 735, 780, 871, 261 is 1
