Given numbers are 209, 520, 805, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 520) = 108680
GCD(209, 520) = ( 209 x 520 ) / 108680
= 209 / 520
= 209
Step2:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 209, 520, 805, 965 is 1
