Given numbers are 969, 945, 285, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(969, 945) = 305235
GCD(969, 945) = ( 969 x 945 ) / 305235
= 969 / 945
= 969
Step2:
LCM(3, 285) = 285
GCD(3, 285) = ( 3 x 285 ) / 285
= 3 / 285
= 3
Step3:
LCM(3, 100) = 300
GCD(3, 100) = ( 3 x 100 ) / 300
= 3 / 100
= 3
So, Greatest Common Divisor of 969, 945, 285, 100 is 1
