Given numbers are 329, 437, 247, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(329, 437) = 143773
GCD(329, 437) = ( 329 x 437 ) / 143773
= 329 / 437
= 329
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 329, 437, 247, 680 is 1
