GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 945) = 233415
GCD(247, 945) = ( 247 x 945 ) / 233415
= 247 / 945
= 247
Step2:
LCM(1, 918) = 918
GCD(1, 918) = ( 1 x 918 ) / 918
= 1 / 918
= 1
Step3:
LCM(1, 779) = 779
GCD(1, 779) = ( 1 x 779 ) / 779
= 1 / 779
= 1
So, Greatest Common Divisor of 247, 945, 918, 779 is 1
