Given numbers are 280, 890, 683, 658
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 890) = 24920
GCD(280, 890) = ( 280 x 890 ) / 24920
= 280 / 890
= 280
Step2:
LCM(10, 683) = 6830
GCD(10, 683) = ( 10 x 683 ) / 6830
= 10 / 683
= 10
Step3:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
So, Greatest Common Divisor of 280, 890, 683, 658 is 1
