Given numbers are 810, 618, 548, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 618) = 83430
GCD(810, 618) = ( 810 x 618 ) / 83430
= 810 / 618
= 810
Step2:
LCM(6, 548) = 1644
GCD(6, 548) = ( 6 x 548 ) / 1644
= 6 / 548
= 6
Step3:
LCM(2, 965) = 1930
GCD(2, 965) = ( 2 x 965 ) / 1930
= 2 / 965
= 2
So, Greatest Common Divisor of 810, 618, 548, 965 is 1
