Given numbers are 645, 209, 114, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 209) = 134805
GCD(645, 209) = ( 645 x 209 ) / 134805
= 645 / 209
= 645
Step2:
LCM(1, 114) = 114
GCD(1, 114) = ( 1 x 114 ) / 114
= 1 / 114
= 1
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 645, 209, 114, 965 is 1
