Given numbers are 969, 643, 315, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(969, 643) = 623067
GCD(969, 643) = ( 969 x 643 ) / 623067
= 969 / 643
= 969
Step2:
LCM(1, 315) = 315
GCD(1, 315) = ( 1 x 315 ) / 315
= 1 / 315
= 1
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 969, 643, 315, 247 is 1
