Given numbers are 680, 850, 663, 819
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 850) = 3400
GCD(680, 850) = ( 680 x 850 ) / 3400
= 680 / 850
= 680
Step2:
LCM(170, 663) = 6630
GCD(170, 663) = ( 170 x 663 ) / 6630
= 170 / 663
= 170
Step3:
LCM(17, 819) = 13923
GCD(17, 819) = ( 17 x 819 ) / 13923
= 17 / 819
= 17
So, Greatest Common Divisor of 680, 850, 663, 819 is 1
