GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(343, 828) = 284004
GCD(343, 828) = ( 343 x 828 ) / 284004
= 343 / 828
= 343
Step2:
LCM(1, 495) = 495
GCD(1, 495) = ( 1 x 495 ) / 495
= 1 / 495
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 343, 828, 495, 649 is 1
