Given numbers are 680, 717, 391, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 717) = 487560
GCD(680, 717) = ( 680 x 717 ) / 487560
= 680 / 717
= 680
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 284) = 284
GCD(1, 284) = ( 1 x 284 ) / 284
= 1 / 284
= 1
So, Greatest Common Divisor of 680, 717, 391, 284 is 1
