Given numbers are 660, 175, 309, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 175) = 23100
GCD(660, 175) = ( 660 x 175 ) / 23100
= 660 / 175
= 660
Step2:
LCM(5, 309) = 1545
GCD(5, 309) = ( 5 x 309 ) / 1545
= 5 / 309
= 5
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 660, 175, 309, 965 is 1
