Given numbers are 749, 979, 307, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 979) = 733271
GCD(749, 979) = ( 749 x 979 ) / 733271
= 749 / 979
= 749
Step2:
LCM(1, 307) = 307
GCD(1, 307) = ( 1 x 307 ) / 307
= 1 / 307
= 1
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 749, 979, 307, 210 is 1
