Given numbers are 785, 357, 669, 343
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 357) = 280245
GCD(785, 357) = ( 785 x 357 ) / 280245
= 785 / 357
= 785
Step2:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
Step3:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
So, Greatest Common Divisor of 785, 357, 669, 343 is 1
